About Convertmaxxing

Convertmaxxing is a media converter that works the way file tools should: you open the page, drop in your files, and get results — no account, no upload progress bar, no “free tier” with a paywall behind it.

The trick is that there is no server doing the conversion. Convertmaxxing runs ImageMagick — the same battle-tested image engine used on servers for decades — compiled to WebAssembly, right inside your browser. When you convert a photo, the bytes never leave your device. There is nothing to upload, which also means there is nothing for us to store, scan, or lose.

That architecture is the whole privacy story, and it's verifiable: open your browser's network tab while converting and you'll see no file uploads. The engine downloads once (about 5 MB), gets cached, and then works even on a flaky connection.

Image conversion is live today — JPEG, PNG, WebP, AVIF, JPEG XL, HEIC (from iPhones), camera RAW files, TIFF, BMP, ICO and more. Video conversion is on the roadmap, built on the same principle: your files stay yours.

The site is free to use and will eventually be supported by unobtrusive ads. Read the privacy policy for the full picture, and the licenses page for the open-source software this site is built on.
