FAQ

Does my data file upload to a server?

No. Conversion runs entirely in your browser using WebAssembly and Web APIs. Open the Network tab in DevTools while you convert — you'll see no outbound traffic carrying your file.

Is this really free?

Yes. No signup, no quota, no upgrade tier. The conversion runs on your machine, so it costs us nothing to host.

Is there a file size limit?

Browser memory is the only ceiling. On a modern desktop browser, a few hundred megabytes works fine. Mobile devices have tighter limits.
