Perceptual Image Hash — frequently asked questions

Is Perceptual Image Hash really free?

Yes. Perceptual Image Hash is free forever on Sada Files — no ads, no premium tier, no watermark, no daily cap that pushes you to pay. Every option on this page is available to everyone.

Do I need to sign up or create an account?

No. There is no account system at Sada Files. Open the page, drop your file, pick your options and save the result. History and saved workflows stay on your device.

Is my file uploaded anywhere?

No. Perceptual Image Hash runs on your device — in your browser using WebAssembly, or inside the free native app. Your file never leaves your computer or phone, which is why there is no upload wait.

Which formats does Perceptual Image Hash accept?

Perceptual Image Hash accepts JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF and HEIC / HEIF. Files are identified by their content, not their extension, so a mislabelled file still works.

Is there a file size or file count limit?

Only what your device can handle. Because processing happens locally there is no server cap, no queue and no "upgrade for larger files" message. Batch as many files as you like.

Can I chain Perceptual Image Hash with other tools?

Yes. After every result a Continue with… menu lists every tool that accepts this output, and the file is handed over in memory. Save the chain as a workflow and re-run it on hundreds of files, or call it in one API request.

Does Perceptual Image Hash work on my phone?

Yes. The web app works on Android and iOS browsers, and the free Sada Files app for Android, iOS, Windows, Linux and macOS runs Perceptual Image Hash fully offline.
