How to convert FLAC to AC3
- Add your .FLAC file - drop it in the box above or click to browse.
- Convert it to .AC3 in a few seconds.
- Download your new .AC3 file.
What to expect
- Lossy encode: AC-3 discards some audio data, so this is not a bit-perfect copy of the FLAC source.
- Channel count is carried over, not created - a stereo source stays stereo, it does not become surround.
- FLAC tags and cover art do not map to AC-3, which is a bare audio stream.
Frequently asked questions
Is quality lost going from FLAC to AC3?
Yes. FLAC is lossless and AC-3 (Dolby Digital) is a lossy format, so some audio is discarded during encoding. The result is fine for playback but is not a bit-perfect copy of the source.
Why convert FLAC to AC3?
AC-3 is the surround-sound format used on DVDs and digital TV broadcasts, so this conversion is useful when audio needs to fit a Dolby Digital workflow that FLAC cannot feed directly.
Where does an AC3 file play?
VLC plays AC-3 on any platform, and Windows Media Player supports it on Windows 10/11. It is also handled natively by DVD and home-theatre equipment.
Will I get 5.1 surround from a FLAC file?
Only if the FLAC already contains multiple channels. AC-3 supports up to 5.1, but converting a stereo FLAC produces stereo AC-3 - the extra surround channels are not invented.
