AC3 Converter - to MP3, WAV, FLAC, M4A and more, free, no upload

Why this runs on your computer

There is no upload: The work happens in this tab. Your file never travels, so there is no copy of it anywhere but your own disk.
Nothing to delete later: Sites that upload promise to delete your file afterwards. That promise only matters because the file was theirs to hold.
It works with the Wi-Fi off: The honest test. Turn off your connection and the tools keep working, because everything they need is already here.

Questions

What can I convert AC3 to?

MP3, WAV, FLAC, M4A and more. AC3 is the surround-sound format that comes off DVDs and broadcast audio, so the usual reason to convert is to get a file that opens where this one does not.

Can a browser really open AC3 files?

Not on its own - Chrome, Firefox and Safari mostly cannot play AC3, which is why most in-browser converters turn AC3 away or quietly upload it. This page brings its own decoder: FFmpeg, compiled to WebAssembly and fetched from this site (10 MB, once) the first time you convert. After that the AC3 file is read entirely in this tab.

Which format should I pick?

MP3 to be sure it plays. FLAC or WAV when nothing may be lost. M4A for Apple devices.

Can I convert several at once?

Yes - drop them all in, and save them one by one or together as a zip.
