About ConvertQuiet

ConvertQuiet is a free online file converter with one core promise: your files never leave your device. Every conversion — images, audio, PDFs, and data files — runs entirely inside your web browser using JavaScript and WebAssembly. Nothing is uploaded to a server, nothing is stored, and no account is required.

Why we built it

Most “free” converters quietly upload your personal photos and documents to their servers. For a one-off conversion of a private file, that’s a lot of trust to hand over. Modern browsers are powerful enough to do this work locally, so we built a converter that keeps your files where they belong: with you.

How it works

When you add a file, it’s read directly by your browser and processed in memory using well-established open-source libraries. The converted file is generated on your device and offered as a direct download. You can confirm this yourself: open your browser’s developer tools, watch the Network tab, and convert a file — you’ll see no request carrying your file anywhere.

Free to use

ConvertQuiet is free. We may show unobtrusive ads to cover hosting, and there’s a tip jar if you’d like to support the project — but the converters themselves stay free, with no sign-up and no watermarks.
