How to convert AVI to MP3
- Add your AVI videos. Drag them onto the box above or click to browse. You can add several at once.
- Pick a quality. 192 kbps suits most uses; choose 320 kbps for the best quality or 128 kbps for smaller files.
- Download. Each MP3 gets its own download button as soon as it’s ready.
What is AVI?
AVI (Audio Video Interleave) is a classic Windows video format from the 1990s, still common on old camcorders, digital cameras and archived home videos. Modern browsers can’t read it directly, so this page uses a built-in version of FFmpeg to pull the audio out and save it as MP3.
Tips
- The first AVI conversion downloads our converter engine (about 30 MB) once; later conversions start straight away.
- Old camcorder audio is often mono or low bitrate, so 128 kbps is usually enough.
- Digitising family videos? Converting the audio makes it easy to share speeches and songs.
AVI to MP3: questions
Why does my first AVI conversion take longer?
Browsers can’t decode AVI natively, so the page loads FFmpeg (WebAssembly) once and caches it.
Can it handle DivX or Xvid AVI files?
Yes — only the audio track matters, and common AVI audio (MP3, PCM, AC3) is supported.
Is my video uploaded?
No. The conversion runs on your device; the video never leaves it.
Are my files uploaded?
No. Anything to MP3 converts AVI to MP3 inside your browser, so your files never leave your device.
