Duplicate Image Finder

Scans a batch of uploaded images and flags visually identical or near-identical duplicates — including resized or slightly recompressed copies of the same photo, not just byte-for-byte identical files — so you can clean up a folder without manually eyeballing every image.

How to use it

Upload a batch of images. The tool compares them using visual similarity rather than just file hashes, grouping likely duplicates together with a similarity score. Review each group, pick which copy to keep, and download the deduplicated set.

FAQ

Will it catch duplicates that were resized or re-saved at a different quality?

Yes — the comparison is based on visual content, not just exact file matching, so a resized or recompressed copy of the same photo is still flagged as a likely duplicate.

What counts as “near-identical” — will it flag similar but different photos too?

The similarity score is adjustable, so you can set a stricter threshold to only catch true duplicates, or loosen it to also surface near-duplicates like burst-mode shots taken seconds apart.

Does it automatically delete duplicates, or just flag them?

It flags and groups them for review — you choose which file in each group to keep before downloading, nothing is deleted without your confirmation.

How many images can I check at once?

There’s no strict cap, though very large batches will take longer to compare since every image is checked against every other one directly in the browser.
