Safe data processing

Your files stay yours

AllConverter is built privacy-first: the entire pipeline is local, so sensitive documents, photos and recordings never leave your machine.

Processed on your device

Every conversion runs inside your browser tab using local WebAssembly engines.

No uploads, ever

Your files are never sent to a server, so there is nothing for us to store or lose.

Nothing retained

Results live in temporary memory and vanish the moment you close the tab.

No account required

No sign-up, no tracking of file contents, no limits placed on your work.
