How to Convert AVI to MP3
Add Your AVI Files
Drag and drop or browse to select AVI videos. This converter reads AVI containers with any internal codec — MP3, AC3, PCM, WMA, or DTS audio streams are all supported.
Confirm MP3 Output
MP3 is pre-selected as the output format. Pick the bitrate that suits your use case — 128 kbps for speech, 192 kbps for balanced quality, 320 kbps for high-fidelity encoding.
Click Convert
Press convert. The AVI container is parsed, the audio track is decoded from its original codec, and re-encoded to MP3 inside your browser using FFmpeg WebAssembly.
Download Your MP3 Files
Download each MP3 individually or grab the full batch. Standard MPEG Layer III output plays on every media player, smartphone, and car stereo without compatibility issues.
