Similar-photo matches use an 8×8 average hash — plain or very similar pictures (sky, white walls) can match by mistake, so check before deleting. Related searches: find duplicate images online free, remove duplicate photos, photo duplicate finder no upload.

Frequently asked questions
Is this duplicate photo finder really free?
Yes — free, no signup, no upload and no limit on how often you use it. Most duplicate finders are paid apps; this one runs entirely in your browser.
How does it find similar photos, not just exact copies?
Exact copies share the same SHA-256 file hash. Similar photos are compared with an 8×8 average image hash — pictures that look almost the same get hashes only a few bits apart, so the tool groups them.
Will it delete my duplicates?
No, never. A browser tool cannot safely delete your files, and we would not want it to. It shows you the groups and the wasted space; you choose what to delete.
Are my photos uploaded anywhere?
No. Every photo is read and hashed only on your device. Nothing leaves your browser — that is the whole point of this tool.
