How to convert AVI to MP3
- Add your .AVI file - drop it in the box above or click to browse.
- Convert it to .MP3 in a few seconds.
- Download your new .MP3 file.
What to expect
- Re-encoding causes a small quality loss; if the AVI's audio is already MP3, use
ffmpeg -i input.avi -vn -c:a copy output.mp3to extract it losslessly. - Output quality is capped by the source - encoding at a higher bitrate cannot recover detail that was not in the original audio track.
- Some AVI files contain multiple audio streams (e.g., two languages); most tools pick the first one by default.
Frequently asked questions
Does converting AVI to MP3 lose audio quality?
Only if the AVI's audio needs to be re-encoded (e.g., AC3 or PCM). If it is already MP3, FFmpeg's
-c:a copy option extracts it with no quality loss at all.How long does the conversion take?
Audio extraction is much faster than video conversion - a one-hour AVI typically produces an MP3 in under a minute on any modern computer.
The output MP3 has no sound - what went wrong?
The AVI may have audio on a non-default stream. Run
ffprobe input.avi to list all streams, then target the correct one with -map 0:a:0.Will the MP3 contain any video?
No - MP3 is a pure audio format, so all video data is discarded when you convert.
