Files stay on your device — nothing is uploaded

Compares images by visual fingerprint, so it also finds duplicates that were resized, re-saved or slightly compressed — not just byte-identical copies. Nothing is uploaded; you decide which files to delete yourself.

Your file is processed in your browser and never uploaded.

Frequently asked questions

Does this also find slightly edited copies?

Yes. The tool compares by visual fingerprint, so resized or re-compressed versions are also recognised as duplicates.

Is my image uploaded?

No. Everything happens in your own browser. Your image never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.

Why in the browser?

PixRust runs entirely in your browser using the Canvas API and WebAssembly. Your image is never sent to a server — all processing happens locally on your device. This means your photos remain private by design, whether they are personal snapshots or confidential documents. There is no account required, no file size limit, and nothing is stored after you close the tab.
