About QuietFiles

QuietFiles is 17 file tools built around one rule: your files never leave your device. Not "deleted after an hour". Not "encrypted in transit". Never sent at all.

Why it exists

Converting a photo or splitting a PDF is a tiny, everyday task, and almost every free tool online asks you to upload the file to a stranger's server to do it. For a format change, that is a trade nobody should have to make. The files people convert are the personal ones: camera-roll photos with GPS coordinates in them, scanned passports, contracts, payslips, medical letters. They should not be posted to an unknown operator to change an extension.

Browsers became capable of this work years ago. WebAssembly runs the same decoders those servers run; Web Workers keep the interface responsive while they do; the Canvas and File APIs handle the rest. The upload step is no longer a technical necessity — it is a habit, and for most operators it is the business model.

How it is built

The site is static HTML, CSS and JavaScript on a CDN. There is no application server, no database, no API, and no account system — not as a design preference, but because none of those things can exist without creating a place your files could go. Processing engines load on demand, after you pick a file, and run in background threads on your own machine. The full architecture is written up here, including how to verify it in your browser's Network tab.

What that costs

Being honest about the trade-offs is part of the point. Processing happens on your device, so a very large file is limited by your device's memory rather than a server's — you will see a clear message rather than a crashed tab when you reach that edge. Some conversions cannot be done in a browser at all, and those tools are simply absent rather than quietly routed through a server. And a tool's engine has to download once before it works offline.
