Common questions

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.

What does 'in-browser conversion' mean?

It means the conversion engine (compiled to WebAssembly) runs directly inside your browser tab, just like a desktop app — but without any installation.

Does this work offline?

Yes. Once the page is loaded, you can disconnect from the internet and the tool will still work perfectly.
