Duplicate Photo Finder

“I've got the same photo four times and my drive is full.”

Two kinds of duplicate, kept apart on purpose: files that are identical byte for byte, which is a fact, and photos that merely look the same, which is a guess. It reads every byte on your own machine, marks which copy to keep, and deletes nothing.

A real SHA-256 fingerprint of every file — same fingerprint, same file, no maybe
Resized and re-saved copies found by a 64-bit picture fingerprint
Guesses and certainties never mixed together in the same list
Marks the biggest version KEEP and gives you a text report with full paths
Cannot delete anything, on purpose — you do that where there's an undo

How it works

Three steps, then you're done

Point it at a folder of photos

Drag the whole folder in. Nothing is uploaded.

Choose how fussy to be

Only changes the look-alikes; identical files are found either way.

Download the list

Then do the deleting yourself, in your own file manager.

Nothing you type ever leaves your computer. There is no account, no login and no server. Switch your wi-fi off and it still works — that's not a promise about our policy, it's just how the tool is built.

Questions

Do I need to install anything?

No. Each tool is a single file. Double-click it and it opens in Chrome, Edge, Safari or Firefox — whichever you already have. No account, no password, no software.

Does anything get uploaded?

No. Your numbers and files never leave your computer — the tools have no way to send them and no internet connection is needed to run them. You can switch your wi-fi off and they still work.

I'm not good with computers. Is this too hard?

The first thing every tool does is walk you through it in five short screens with pictures. Then there's a button that fills it with example numbers so you can watch it work before touching anything.

Will it work on my phone?

Yes. Email yourself the file and open the attachment, or drop the files in iCloud Drive, Dropbox or Google Drive and open them from there — then they're on every device you own.
