Privacy Policy

The short version

Refom converts files inside your own browser tab. Your files are never uploaded, stored on a server, or seen by anyone at Refom — because there is no server in the conversion path to see them.

What actually happens when you convert a file

When you drop in a file, it stays in your browser’s memory. Image, PDF, spreadsheet, document, data, archive, and font conversions all run using your browser’s built-in Canvas and File APIs. Audio and video conversions run using FFmpeg compiled to WebAssembly, executing entirely on your device.

The one network request Refom makes on your behalf is a one-time download of that audio/video conversion engine from jsDelivr, a third-party content delivery network — that’s the program that does the converting, not the file you’re converting. Your browser caches it after the first use. Every other format makes no network request at all once the page has loaded.

Cookies, accounts, and analytics

Refom doesn’t use cookies, doesn’t ask you to create an account, and doesn’t run any analytics or advertising trackers. The only thing Refom stores is your light/dark theme preference, saved in your browser’s local storage so it’s remembered on your next visit — that preference never leaves your device either.
