Programs for finding duplicate photos. Programs for finding identical photos on a computer

Perhaps today there is no person who would not actively use a computer or other portable devices. As a rule, over time, a huge number of absolutely identical files accumulate on a PC. Searching for and deleting them manually is quite tedious and time consuming. Fortunately, today you do not have to rack your brains about how to perform these manipulations. Developers of modern applications have long come up with programs for finding duplicate photos on a computer. Consider the best of them, as well as the types of graphic files that often have to be deleted.

What are the same photos

As a rule, on laptops of several categories:

• identical files. And in this case, we are talking about situations where users simply copy the same files and paste them into other folders on the computer.
• Image with the same titles. This often happens when using cameras of different brands. As a rule, they assign the same file names.
• Bad shots. Today, professional photographers very often use continuous shooting of an object. The result is just a fantastic number of the same photographs, differing only in some meager nuances.
• Changed images. In this case, we are talking about those photographs that have been reduced, enlarged, mirrored or modified.

On the Internet, a program for finding duplicate photos is easy to find. The main thing is to install them correctly.

How to download

It is best to look for programs to find and remove duplicate photos on the official websites of developers. As a rule, software developers provide users with the ability to use truncated versions of utilities.

Downloading apps from unofficial sources is fraught with consequences. Very often in a folder with boot files turn out to be viruses.

Duplicate Cleaner

This tool does a great job of finding and removing duplicate photos on portable computers. To get rid of unwanted files that only slow down your work hard drive and take up a lot of free space, just use Duplicate Cleaner, which cleans up network and local drives. In addition, the application also finds the same audio, video files and text documents.

If we talk about the main features of this utility, then you should pay attention to the fact that the search is carried out not only by name, but also by the contents of the files. In this case, you can set custom settings. Sound files are scanned in all known and currently valid formats.

While running the program for finding duplicate photos, you can export and import search results in CSV format. Also, the user can track and view the size, date of creation and other data about the files. This helps you decide which documents are the best to delete.

AntiDupl

This program for finding identical photos allows you to quickly recognize all duplicate documents on your computer's hard drive. This tool is absolutely free, in addition, it supports an interface in several languages, including Russian.

The utility works very quickly and has minimal requirements for system resources. Moreover, the program does not even need to be installed, it is enough to copy it to a flash drive and use it in any directory.

The application perfectly processes a large amount of information and allows you to quickly detect entire lists of identical files. The main window of the program contains the main controls, the meaning of which becomes clear on an intuitive level, so even an inexperienced person can use the utility.

Among the most interesting options is the ability to search for defective files. You can also select the type of documents that may be lost during the search. In addition, the program for finding duplicate photos in Russian allows you to search for files even in subdirectories and hidden folders.

In the settings, the user can specify whether he wants to delete mirrored images or those files in which images have been resized. Thanks to such flexible parameters, a very fast and high-quality removal of all duplicates occurs. At the end of the application, a detailed report is issued.

CloneSpy

This is a very small utility that will quickly clean your computer of unnecessary files. Immediately after installation and the first launch of the program, automatic search and control fixation of all files that are in the system. At the same time, the application completely ignores the date of creation, size and other indicators of documents.

However, in the menu of this program there is no option to disable the display of files with the same name. However, if you consider that this is a free product, then you can put up with some nuances.

Image Comparator

This duplicate photo finder is very popular among users. By and large, it can be considered the most productive and functional.

Available both paid and free version this application. If we talk about the advantages of the program, then you should pay attention to the fast speed of searching and displaying duplicates. This is the optimal solution for those who store terabytes of information on their computer for a huge amount of time.

However, it was not without drawbacks, which drew the attention of many users. The main drawback is visible after installing the application. The program interface is very inconvenient. The same goes for file handling.

In order to view the desired file, you will have to select it and click the arrow. Only then can the document thumbnail be displayed in the main window. And what about those who have more than 200 photos that you want to delete or process? In this case, it will be necessary to perform manipulations 400 or more times. In this case, the user also needs to remember the names of those files that they need.

Also, many noted a not very convenient method for finding duplicates by the number of similar pixels. 'Cause on the one hand say it's the best program to search for duplicate photos is very difficult, but on the other hand, the utility has a lot of flexible settings.

VisiPics

This application beats all records in terms of the number of downloads abroad. On the one hand, this is due to the fact that this is a free version and there may be big problems with access to such applications. But, according to reviews, it really has a lot of positive qualities. Among them, it is worth noting the excellent functionality. The settings are very sensitive, thanks to which the user can independently adjust the mechanism for searching for similar source images.

Displaying the same files is really very fast and high quality. However, many have noticed that this program for finding duplicate photos is a little more tied to the light of the picture, which in some situations can lead to confusion.

If we talk about the shortcomings, then, according to user reviews, they also drew attention to the inconvenience of the interface. You can view photos in an enlarged view only after the cursor is held on the image for a very long time. At the same time, a miniature with a resolution of only 48 pixels is issued, it is very difficult to see anything on it. Therefore, it is inconvenient for an experienced photographer to use the program.

It is also worth considering that the utility interface is not translated into Russian, so for those who do not speak English, it will be quite difficult at first.

Photo Database 4.5

This program for finding duplicate photos is very often used by specialists when working with photos, not only to find identical files, but also for many other functions.

Starting with version 4.5, the utility has a new folder called "Collection", where you can find the "Duplicates" category. She is just responsible for finding the right files. When you open this directory, the program automatically searches for duplicate photos.

The utility also provides quick navigation, which is responsible for jumping to folders with selected images. Removal is done in a very convenient way. To do this, simply select all junk files in Explorer using keyboard shortcuts. Then it is enough to press only 1 "Delete" button. All selected photos are moved to the trash and removed from the collection.

Also available automatic deletion files. To do this, just click the appropriate button, which is located on the bottom taskbar. You can also select multiple images and get rid of only them.

Finally

This article has reviewed free utilities, which can be easily found in the public domain or downloaded via torrents. They are more suitable for home private use. Of course, there are also commercial versions of almost all programs. However, such great functionality is not always needed by a person who just wants to quickly delete the same files. As a rule, they are used only by experienced photographers who constantly work with a huge number of images.

Good day.

I think that those users who have a lot of photos, pictures, wallpapers have often come across the fact that dozens of identical files are stored on the disk (and there are hundreds of similar ones ...). And they can take up a lot of space!

If you search for similar pictures on your own and delete them, then there will not be enough time and effort (especially if the collection is impressive). For this reason, I decided to try one utility on my small wallpaper collection (about 80 GB, about 62000 pictures and photos) and show the results (I think many users would be interested in this). So…

Search for similar images in a folder

Note! This procedure is somewhat different from searching for identical files (duplicates). It will take significantly longer for the program to scan each image and compare it with others to find similar files. But I want to start this article with this method. A little lower in the article I will consider the search for full copies of pictures ( this is done much faster).

On fig. 1 shows the experimental folder. The most common, on the most ordinary hard drive, hundreds of pictures were downloaded and uploaded to it, both their own and from other sites. Naturally, over time, this folder has grown greatly and it was necessary to “thin out” it ...

Image Comparer(scan utility)

Official site: http://www.imagecomparer.com/rus/

A small utility for finding similar pictures on your computer. It helps to save a lot of time for those users who work with pictures (photographers, designers, wallpaper collectors, etc.). Supports Russian language, works in all popular Windows OS: 7, 8, 10 (32/64 bits). The program is paid, but there is a whole month for testing to make sure of its abilities :).

After launching the utility, a comparison wizard will open in front of you, which will guide you step by step through all the settings that you need to set to start scanning your pictures.

2) On my computer, the pictures are saved in one folder on one disk (therefore, there was no point in creating two galleries ...) - it means a logical choice " Within one group of images (gallery)”(I think that for many users things are about the same, so you can immediately stop your choice on the first point, see Fig. 3).

Rice. 3. Gallery selection.

3) In this step, you just need to specify the folder (folders) with your pictures, which you will scan and look for similar pictures among them.

4) In this step, you need to specify how the search will be performed: similar images or only exact copies. I recommend choosing the first option, so you will have more copies of the pictures that you hardly need ...

5) The last step is to specify the folder where the search and analysis result will be saved. For example, I chose the desktop (see Fig. 6) ...

Rice. 6. Selecting a location to save the results.

6) Next, the process of adding images to the gallery and their analysis begins. The process takes a long time (depending on the number of your pictures in the folder). For example, in my case it took a little over an hour…

7) Actually, after scanning, you will see a window (as in Fig. 8), which will show pictures with exact duplicates and pictures very similar to each other (for example, the same photo with different resolutions or saved in a different format, Fig. 7).

Rice. 8. Results…

Advantages of using the utility:

1. Freeing up space on your hard drive (and, sometimes, significantly. For example, I deleted about 5-6 GB of extra photos!);
2. An easy wizard that will guide you step by step through all the settings (this is a big plus);
3. The program does not load the processor and disk, and therefore, when scanning, you can simply minimize it and go about your business.

Minuses:

1. Relatively long time for scanning and gallery formation;
2. Similar pictures are not always similar (that is, the algorithm sometimes makes mistakes, and with a degree of comparison of 90%, for example, it often produces little-similar pictures. Actually, manual “moderation” is indispensable).

Search for identical pictures on a disk (search for complete duplicates)

This option for cleaning the disk is faster, but it is quite “rough”: to remove only exact duplicates of pictures in this way, but if they are of different resolutions, the file size or format is slightly different - then this way is unlikely to help. In general, for regular quick "weeding" of the disk - this method is better, and after it, it is logical, you can look for similar pictures, as described above.

Glary Utilities

Often we have similar photos, unsuccessful shots, or the same pictures are in different folders on our hard drive. The more a person is fond of photographs, the more such files can be stored on a computer, taking up free space. To find the same photos on your computer, let's turn to third-party programs for help.

What are the same photos

Consider which duplicate photos are usually stored on a computer:

1. Completely identical files:
   as a rule, are formed when copying the same folders with photos to different places for safety.
2. Photos with the same filename:
   may appear if you use different cameras of the same brand. In fact, they are not the same photos, but can be accidentally deleted when visually comparing file names without viewing their contents.
3. Bad shots:
   with the departure from the mass circulation of film for photographs, there was no need to control the number of frames taken. Which, in turn, made it possible to take as many photos as required, and then select the most successful ones. Unsuccessful frames are often visually very similar to successful ones, with the exception of small things: a blinking person, a blurry frame, a random object in the shooting field.
4. Modified photos:
   reduced or enlarged copies, photos with captions added, cropped in the image editor.

Consider two popular programs for finding duplicate images and compare their capabilities. To do this, let's take a photo of a famous cat, make several copies of it with different changes, and put all the files in one folder.

Method 1: Awesome Duplicate Photo Finder

Free program that does not require installation. Thanks to its simple interface, it allows you to quickly check folders for duplicates. Russian language is missing.

Download Awesome Duplicate Photo Finder

1. 1. We start the program.

1. 1. Select a folder to search by clicking on «+» .

1. 1. After pressing the button Start search we get a table with the results and a window for comparing the two selected files.

The program shows the percentage of similarity between two images and offers three options for each:

1. • move- Move;
   • Browse— Show the selected file in the folder;
   • Delete- Delete.

Method 2: AntiDupl.NET

Free open source program with Russian language support. We will show its capabilities in the same four photographs.

Download AntiDupl.NET

1. 1. We start the program.

1. 1. To start the search press "Search" and choose "Ways".

1. 1. Add folders to be searched and click "OK".

1. 1. Start the search in the selected folders by clicking "Search" and then "To start searching".

1. 1. After the search is completed, the main window displays a comparison of the two images in the table of found matches.

The program was able to find a duplicate photo and in the recommendations column advises deleting one of the files.

IN this case the application has found two similar images and shows their differences by highlighting in red in their properties (file size, image size, compression ratio, blur level).

Conclusion

The difference between the work of these two programs is minimal, but for some users the presence of the Russian interface is the main plus.

Everyone has a folder on their computer in which they store various photos or images, and it often happens that duplicates of such files appear on the hard drive. The question immediately arises, how to quickly get rid of them. The article will list a number of programs that are able to perform such actions quickly and efficiently.

It is a simple and easy to use program that is able to search in several ways and create galleries from selected images. What sets it apart from other tools is the presence of an assistant window, which makes using Duplicate Photo Finder even easier. Among the minuses, one can single out paid distribution and the absence of the Russian language.

Duplicate Photo Cleaner

Duplicate Photo Cleaner is also an easy-to-use program that can also read a wide range of graphic object formats. It has several ways to search for duplicates, and the presence of a Russian-language interface distinguishes it from most of the solutions described here. At the same time, Duplicate Photo Cleaner is paid, and the trial version has very limited features.

Duplicate File Remover

Another powerful tool for finding duplicate photos is Duplicate File Remover. In addition to searching for images, it is also able to scan your computer for other identical files. The capabilities of Duplicate File Remover significantly expand the plugins that are installed with it, but you can activate them only after purchase license key. Another disadvantage is the absence of the Russian language in the settings, but this does not prevent you from using Duplicate File Remover for its intended purpose, since all actions here are performed on an intuitive level.

Duplicate File Detector

This is a powerful multi-tasking program that is able to instantly find the same documents in the specified directory. Duplicate File Detector supports a large number of formats that will be checked during operation. This is the only tool we have reviewed that provides the ability to hash any file, for which there is a built-in hash calculator. Thanks to the latter, you can get the result in 16 hash codes. Using the Duplicate File Detector, you can rename the selected group of files according to one of the proposed templates. The program has been translated into Russian, but it is paid.

ImageDupeless

ImageDupeless is a powerful tool for finding duplicate images on your computer. In terms of its functionality, it is very similar to the previously described Duplicate Photo Finder. The same assistant is present here, the same possibilities for searching for identical graphic files and the function of creating a gallery from images. But ImageDupless has a Russian-language interface, which distinguishes it from the background of the mentioned program. The main disadvantage can be considered paid distribution and the fact that a lot of features are available only after purchase.

DupKiller

DupKiller is one of the best ways to find not only duplicate images, but files in general. It provides the ability to search almost anywhere on the computer, has a very wide range of settings, and supports plug-ins. In addition, it is distributed completely free of charge and translated into Russian, which makes it possible to use it without any restrictions.

AllDup

AllDup is small free program, which is designed to search for identical (including graphic) objects on the hard drive. It supports a large list of formats, which guarantees a high-quality search for duplicates. AllDup will also be a great option for computers that are used by several people at the same time. Against the background of the rest, it is distinguished by the ability to create several profiles with certain settings. This feature will save a lot of time for users, which would be spent on reconfiguring the program. You can also add the presence of the Russian language and free distribution by the developer to the list of AllDup's positive qualities.

Dupe Guru Picture Edition

Using DupeGuru Picture Edition, the user will receive a free, simple and straightforward duplicate photo search engine on a computer with a Russian-language interface. Among additional features it is worth highlighting that here you can export the results to a browser or to a CSV format that is readable by .

Dup Detector

Dup Detector is probably the simplest utility on the list provided. It does not have the Russian language and any additional features, except for creating galleries from images, but at the same time it provides several options for finding duplicate photos. In addition, Oak Detector is distributed by the developer absolutely free of charge and supports a large list of graphic formats.

This article reviewed programs that can quickly and effortlessly detect duplicate photos on a hard drive and permanently delete them. Which tool to use, let everyone decide for himself, but you should know that any of them will 100% cope with the task.

“On March 3rd, during a big storm on the East Coast, I headed out to the ocean to capture wave activity. The road took me to the Great Island Common, New Castle, New Hampshire, where the Wailback Lighthouse is visible, standing 12 kilometers from the coast. I was hoping to photograph the big waves crashing around the lighthouse and Mother Nature did not disappoint.

The Great Island Common is a vast open park where people come for picnics in summer and warm winters.

Upon arrival, I set up my Canon 5D Mark IV DSLR with a Sigma 150-600mm lens on a tripod, positioned to the right of the tree to shelter from the gusts of the north wind. Many people know how difficult it is to keep a 600mm lens stable in strong winds, even when using a tripod.

I set up the camera and waited until I saw the wave begin to hit the lighthouse. Then I continued to shoot until the series ended, not knowing how the wave would behave. Most of the shots failed, but about three shots out of all that were taken over the course of about 45 minutes turned out to be pretty decent.

When I got home, I chose one image to edit and uploaded it to Instagram. When a local TV station shared the photo on their Facebook page (with my permission), it was immediately followed by numerous reposts, comments and likes.

But one comment said I stole an image from another New England photographer, Erica Gendon. I first told the commenter that this was really my shot and that I had the original RAW file, and then I looked at another photographer's page and was amazed. We had the same images, shot with millisecond precision, seemingly from the same perspective and location.

This photo was taken by me, Ron Riesman.

Photo by Eric Gendon.

Leaving out the Lightroom processing, the photos look virtually identical at first glance, except for the water in the foreground and the different placement of a few patches of white foam. But even they turned out to be identical in size and shape, and I know that such elements are easily moved using the stamp tool in Photoshop, so I was worried: maybe my image was stolen and slightly changed?

Initially, I only had access to a low-res image of him, so I couldn't make out the smallest details, which eventually helped me make sure we both had the originals. But after overlaying the images in Photoshop, I was amazed: the lighthouse and the waves matched almost to the pixel. The differences in the water in the foreground and the white caps of foam on the horizon kept me from claiming he stole my shot.

Another local photographer compared my photo with the higher resolution version of Eric's and noticed that the distance between the vertical strips of iron railing around the top of the lighthouse was slightly different compared to my image. This meant that the other photographer was most likely standing slightly to the left of where I was.

Location of photographers.

Because the 60D that Gendon shot with has an APS-C sensor, he was probably a little further away, which would have compensated for the 1.6x crop factor or used a shorter focal length. And that would explain the difference in the location of the white foam.

However, the lighthouse and the breaking wave exactly matched, which is surprising, since the pictures were taken by chance by two different photographers.

I didn't know Eric, each of us chose this place randomly, we both shot with different cameras (60D and 5D Mark IV) with different sensor sizes; in 60D continuous shooting mode at a frequency of 5.3 frames per second, 5D Mark IV - 7 frames per second. We both used 600mm focal length; aperture, shutter speed and ISO settings are also almost the same (F/8, ISO 400, 1/1600s and F/8, ISO 320, 1/1000s). We ended up both choosing the same photo from that day to post online, only to find out later that we were only 28 meters apart.

I did a Google search to check how often this happens, and I could only find one article from 2011 that featured two photographers filming a surf competition in Huntington Beach who took nearly identical shots of a surfer and the movement of a wave.

If you've shot water in continuous burst mode, you know how different each exposure is, even if the time difference is only 1/7 second between shots. For five years, I have been running night sky photography workshops with more than 200 photographers who often focus on the same subject, shooting with similar cameras and lenses at the same time, even using continuous time-lapse photography. But until now, I have never seen two images so similar, as if they were virtual clones.

While this is a rare occurrence, I think as cameras get faster and photographers get better prepared for shooting, this kind of thing will become more frequent. This happens daily with stationary or slow moving objects (buildings, sunrise/moon), but almost never with moving water.”
