  3. Click Convert All. FFmpeg runs inside your browser through WebAssembly; nothing is uploaded.
  4. Download your .m4a files as soon as each one finishes.

Frequently asked questions

Is it safe to convert FLV to M4A here?

Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.

Is there a file size limit?

There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.

Can I convert several FLV files at once?

Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
