What is an AC3 file?
AC3 – Dolby Digital (AC-3) audio. AC3 is Dolby Digital: the audio of DVDs, many Blu-rays and TV broadcasts, up to 5.1 channels. Files for home cinema equipment use it. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Good to know
- The sound is decoded and written as a WMA file at a fixed quality (192 kbit/s).
- Both are lossy, so converting costs a little quality each time: keep the original and convert from it when you can.
- Tags such as title and artist are kept where the new format has room for them. Only the first audio track is converted; pictures and video are left out.
Frequently asked questions
Is converting AC3 to WMA free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my AC3 files uploaded anywhere?
This conversion runs on our server, because converting audio needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the AC3 file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the WMA look the same as the AC3?
It sounds very close: the sound is encoded again as WMA at a fixed quality, so a little detail is lost, and tags such as title and artist are kept where WMA has room for them.
Can I convert several AC3 files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
How long does converting AC3 to WMA take?
In our tests a one-hour WAV recording became an M4A file in about 46 seconds. A song of a few minutes takes a few seconds, and most conversions cost a single credit.
