About

Built because file converters shouldn't need your files.

File converters have always disappointed us. They're slow, require accounts, and send your files to third-party servers you know nothing about. We decided to fix that.

Every single file you convert — images, audio, video, and documents — is processed entirely on your device using WebAssembly. Nothing ever leaves your browser. There are no servers involved, no uploads, and no one can ever see your files.

Principles
01

Your files stay on your device

Every tool runs locally in your browser via WebAssembly. There is no server. Your files are never uploaded, transmitted, or stored anywhere.

02

Free, no account, no strings

No signup, no email, no payment wall, no file size limits. Open the site, use the tools, close the tab. That's it.

03

Open source, verifiable

The entire codebase is public under AGPL-3.0. Don't trust us — read the code. Every privacy claim is verifiable.

Origin

This project started as a fork of VERT.sh (AGPL-3.0). We've since rebuilt the brand, added 30+ tools, redesigned the interface, and expanded to 28 languages — but the core conversion architecture traces back to the VERT team's excellent work.
