Duplicate Image Finder
Find and remove duplicate photos from your computer in minutes. Unlike basic duplicate file finders that only match identical files, this tool compares actual image content - so it catches the same photo saved under a different name, converted to another format, or lightly edited.

Why Remove Duplicate and Similar Photos
Reclaim Disk Space
Duplicate and similar photos quietly consume gigabytes of storage. Windows has no tool to find them - content-based scanning typically recovers several GB even on a modest library, in minutes rather than hours of manual sorting.
Find Your Photos Faster
A library full of near-identical shots makes it harder to find the image you actually want. Clearing out redundant copies leaves a clean, organized collection where every photo is easy to locate.
Speed Up Your Applications
Photo managers, backup tools, and cloud sync services have to process every file in your library. Fewer redundant images means faster indexing, quicker backups, and less bandwidth wasted uploading files you don't need.
How to Find and Remove Duplicate Photos
Most photo libraries accumulate duplicates gradually - the same shot saved twice after editing, a backup that was never cleaned up, photos imported multiple times from the same card. The problem is that standard file tools can't detect them. Two files can look identical on screen while being stored completely differently on disk, which is why a filename or size check misses so many real duplicates.
This tool takes a different approach: it decodes each image and compares the picture itself, not the file data. That's what allows it to catch the same photo saved as a JPG and a PNG, a resized copy sitting in a subfolder, or an edited version with a different filename - matches that a generic duplicate finder walks straight past.
Three Steps to a Clean Photo Library
1. Add Folders
Drag folders into the app or use the Add Folder button. Works with local drives, external hard drives, USB sticks, and network locations.
2. Scan for Similar Photos
Set a similarity threshold and run the scan. The app compares image content directly and groups matches together - exact copies and near-duplicates alike.
3. Review and Delete
Browse the grouped results and select what to remove, or let auto-mark pick the lower-quality copies automatically. Delete, move, or back up in one click.

Key Features
What sets this tool apart from a basic file comparison utility.
Compares actual image content using an AI algorithm - not file names, sizes, or checksums. Finds matches across formats and catches edited or resized versions of the same photo.
Handles all common formats including JPG, PNG, WebP, HEIC, AVIF, PSD, and a wide range of RAW camera files from Canon, Nikon, Sony, Fujifilm, and others.
Include or exclude file types and folders, set source folders to protect from deletion, adjust the similarity threshold, and keep the highest-quality version automatically.
Move duplicates to a temporary folder, send them to the Recycle Bin, or delete them permanently. Preview before removing anything to make sure nothing important is lost.
Search your library using a sample photo to find all similar matches. Compare two or more folders against each other rather than scanning everything together.
Uses CPU hardware acceleration and a fingerprint cache so large libraries scan quickly and repeat scans run even faster. Tested with over one million images.
Scan Modes
- Similar Images - compares actual image content to find visually similar photos regardless of format or filename.
- Exact Duplicates - lists only byte-for-byte identical files stored in the same format. Very fast.
- File Size - groups files by size for a quick first pass. Useful for large libraries where speed matters most.
- Time Difference - finds photos taken within a set time interval, useful for grouping burst shots or photos from the same session.
- Similar EXIF Tags - matches on camera model, lens type, description, or other embedded metadata.
