Find and remove duplicate photos using the award-winning Visual Similarity Duplicate Image Finder rated OUTSTANDING on CNET.
With the growing numbers in megapixels and count of devices that take pictures user image collections occupy bigger and bigger portions of the hard drives. These large image collections include a lot of duplicates, but identifying and deleting them can be a major hassle. If you're running low on disk space, duplicate files of any type can be a problem.
Finding duplicate photos brings its own challenge. Because of the way we take digital pictures and manipulate them, we often end up with multiple versions of the same photos, as well as separate but near-identical images. For instance, your hard drive may contain an original, full-sized picture, and a smaller version you e-mailed to a friend, or original and a cropped one. It is common to also apply light adjustments, conversions to black and white, and experiments with photo-editing tools. There are also the near-identical pictures taken in the camera's burst mode. If you're trying to slim down your Pictures library and organize photos, you'll want to find all of these and decide which ones to keep.
Our duplicate picture finder tool can solve this issue and remove gigabytes of duplicate images and also help to put an order in a large photo collections.
The special thing about VSDIF as the name already suggests is the fact that it can find similar photos even if they are stored in various image formats and do not include any EXIFF information or tags.
The true photo analysis allows VSDIF to find identical photos even if they are stored in completely different file formats. This is not something that a fuzzy search or duplicate finder tool can achieve. More than 100 popular image formats and more than 300 RAW camera formats are supported.
All duplicate photos that are similar more than a predefined percent will be group together by similarity and listed in a detailed table. The percentage of similarity can be increased or decreased in order to broaden or narrow the listed items.
There is internal image preview that will display the duplicate photos side by side for easier quality assessment and comparison. Double-clicking the preview will display the image in full size for more details.
An option to exclude certain folders from auto-check or "self-scan" helps to compare two or more folders with photos against each other. The "Exclude from self-scan" option means that the pictures inside the marked folder will not be compared with each other, but will rather be compared only with images located in other folders.
VSDIF is extremely optimized in terms of CPU and memory usage. The tool can easily compare millions of images. Unfortunately in order all that data to be processed it should be READ from the storage and then analyzed. Reading the files from your hard drive is usually the slowest part of a duplicate scan. As this is a hardware related limitation it means that a faster hard drive will help for a quicker scan.
The best performance optimization can be achieved using the optimized photo cache system introduced in the latest version. Using the cache system VSDIF will collect and store information for the scanned images and reuse it for consequential scans. Reusing this information the duplicate image finder can scan thousands of photos in less than a second. Cached photos are also checked for modifications, so even if the images included in the cache are altered they will be re-processed and the latest version will be used for the comparison.
Auto-check is an advanced feature that will automatically mark duplicates for deleting based on various photo properties and keep ONE item from every duplicate picture group. By default VSDIF will mark all images with smaller dimensions or images with smaller size if dimensions are equal.
There is an option to search for images inside an image collection. In order to use this feature the folders to be searched should be loaded in the folders list. Opening the image search dialog prompts the user to load one or more sample images. Starting the image search will scan the photo library and display all the images that are similar to the loaded samples. The percentage of similarity can be altered in the application prior to starting the search. This photo search method can also utilize the cache system for better performance.
