Find and Remove Similar & Duplicate Photos
Image Comparer is a Windows duplicate photo finder that matches pictures by visual content — not file names, dates, or checksums alone. It finds exact copies and near-duplicates: burst shots, resized exports, recompressed JPEGs, rotated or flipped images.
What you can do
- scan one folder or compare two folders for look-alike photos
- set a similarity level to catch similar photos, not only byte-identical files
- review pairs side by side with highlighted differences
- auto-mark higher or lower quality images, then delete, move, or copy in one click
- work with large libraries: JPEG, RAW, HEIC, WEBP, PNG, TIFF, PSD, and more

How it works
1. Scan by image content
Point Image Comparer at your gallery. It analyzes how photos look, then groups exact duplicates and similar images. You choose the similarity threshold — so burst sequences and re-saved copies show up together even when file sizes differ.
2. Compare and clean
Review matches in pairs or as a top-ten list of look-alikes. Tick what you do not need; see how many files and how much disk space you will free. Delete, move, or copy in bulk — or let the program prefer higher/lower quality automatically.
3. Keep the collection clean over time
After the first pass, add new photos to the same gallery. Image Comparer compares newcomers to what you already cleaned, so fresh duplicates are easier to catch before they pile up again.
Who it helps
- Photographers — cull series and keep the best frame; RAW formats supported.
- Anyone with a messy photo library — phone dumps, WhatsApp exports, old backups full of near-copies.
- Collectors and webmasters — unique libraries without wasting disk on look-alike files.
FAQ
Exact duplicates vs similar photos?
Use a high similarity setting (up to 100%) for identical files. Lower it to find similar photos — same scene, different exposure, crop, or resolution. That near-duplicate search is what most “checksum only” tools miss.
Is the download free to try?
Yes. You can scan and review duplicates as long as you like — there is no time limit. Moving, deleting, or copying marked files needs a license once you are sure it works for you.
Windows versions?
Windows 7, 8, 10, and 11.
