The hard drive of our computer is usually used to install games, applications, as well as to store music and of course our photos. If we like to accumulate photos it is possible that more than one we have it duplicated, either because we have downloaded it more than once without realizing it or because someone sent it to us several times. To solve it, there is a program like Image Comparator , which allows us to locate duplicate images so that we can clean up and organize our files.
If we want to look for duplicate photos on our computer, soon that we have a good amount of stored photos it will be quite a complicated and tedious task. Therefore, to carry out this task, we can use Image Comparator, which is in charge of comparing the pixel-by-pixel data of all the photos, even if two images have different formats and file sizes, in order to detect the They may be duplicated so that we can review and delete them.
Use Image Comparator to find duplicate photos
Download Image Comparator
To start looking for duplicate images, the first thing to do is download Image Comparator from its SourceForge page . It is a free and portable program, so it does not require any type of installation and works under the Windows operating system. We only have to download the zip file, and when we unzip it we will find the executable for 32 and 64 bit systems. It is not a program that is characterized by its support, since the latest version dates from 2014, but it should not be an impediment for it to carry out its work correctly.
Learn how to find duplicate images
Once we run it, its main menu will appear immediately, which, although it is in English, can be interpreted without many problems. Next, we must click on the Add Folder button and add the main folder in which we want the application to search for duplicate images. We do not have to worry about the subfolders since the program will also be in charge of scanning them for duplicates, although this is something that can be configured as we will see later.
Once added, we will see a button called Compare , where we must indicate what is the number of pixels to compare. By default it sets 1000 pixels chosen at random. Now we will click on Find Duplicates to start the search among all the images in the folder, being compatible with the JPG, TIF, PNG, ICO, GIF and BMP formats, which are the most popular when it comes to saving our photos, although they are it lacks that it cannot find files in RAW format.
Once the search is finished, the duplicate files will appear, so we must confirm that this is the case. For this we must press the button with a double date (>>) that we will find on the right side of the window. Pressing will open a window from where we can see both images to verify that they are indeed duplicates.
Once checked we now have three options available. If we want to delete it because the image is effectively duplicated, we must press the Delete Selected button. If we click on Remove from list , we will delete the entire list of images found and if we click on Clear it will delete the location we have selected for the search of the photos.
From its Options tab it is possible to configure some parameters, so that we can predefine the search formats, choose removal methods, select whether or not we want to search the subfolders, skip files of different sizes, or delete Automatic damaged files.
Alternatives to Image Comparator
If we need a program that helps us find duplicate photos on our computer, we can choose some of these alternatives to Image Comparator.
Find.Same.Images.OK
It is an application with which we will be able to find duplicate images with great solvency thanks to the fact that it compares them at the pixel level, so it will be easy to find all kinds of equal images, even if they are different in size or rotated. We can download it for free from its website .
Visual Similarity Duplicate Image Finder
With this program we will be able to search for duplicate images with great visual similarity since it uses sophisticated and complex algorithms. It also allows you to customize the search by percentage of similarity and is compatible with JPEG, GIF, PNG, TIF, JP2, TGA, PCX, BMP, WMF, WMF, ICO, RAW, HDP and PSD formats. This application has a cost of $ 24.95, and allows you to download a free version from its website with some limitations.
Anti-Twin
It is a small application that is in charge of comparing files to look for duplicate or similar files on our hard drive, being able to eliminate them from the same application. In this way, it not only finds duplicate images but also other types of files. Anti-Twin is a free application that can be downloaded from the developer’s website .
