Progressive JPEG / Interlaced PNG — frequently asked questions

Is Progressive JPEG / Interlaced PNG really free?

Yes. Progressive JPEG / Interlaced PNG 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. Progressive JPEG / Interlaced PNG 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 Progressive JPEG / Interlaced PNG accept?

Progressive JPEG / Interlaced PNG 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 Progressive JPEG / Interlaced PNG 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 Progressive JPEG / Interlaced PNG 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 Progressive JPEG / Interlaced PNG fully offline.
