Drop a folder of photos and find every duplicate - identical files and look-alike copies that were resized, re-saved or lightly edited. The best copy is picked for you, and you can download only the unique images. Want to see two of them in detail? Use Image Compare.

The finder never deletes anything - your originals stay where they are. Use the CSV list to clean up, or keep the ZIP of unique images.
| Kind | How it is found | Example |
|---|---|---|
| Identical | Same bytes (SHA-256) | The same photo downloaded twice |
| Near-identical (Strict) | Visual hash, 0-4 bits apart | Re-saved as JPG, resized |
| Similar (Normal) | Up to 10 bits apart | Recompressed, small colour change |
| Loosely similar (Loose) | Up to 16 bits apart | Crops, filters, burst shots |
The visual hash shrinks each image to 9 x 8 pixels and records where it gets brighter or darker. Copies keep the same pattern even after resizing or compression.
In every group the image with the most pixels is marked Keep; on a tie, the larger file wins.
Click any image in the group to keep it instead.
The ZIP holds every image that is not a duplicate plus one kept copy per group, in their original folders.
Drop a folder or a batch of images into the box. Identical files and look-alike copies are grouped side by side within seconds.
Yes. The visual hash ignores size and compression, so a resized or re-saved JPG is grouped with its original. Use Loose to also catch crops and filters.
No. A website cannot delete files on your computer. You get a CSV list of duplicates and an optional ZIP of only the unique images.
Up to 2000 at a time, depending on your device memory. Large libraries work best in batches.
JPG, PNG, WebP, GIF, AVIF, BMP, SVG and ICO. Convert HEIC and TIFF first with HEIC to JPG or TIFF to JPG.
No. Every image is read and compared in your browser and never leaves your device.
