Convert AVI to MP3: Audio From Old Videos

AVI is the format of many older digital cameras, camcorder transfers and Windows video tools. If you only need the sound (a talk, a family recording, a song), this saves it as an MP3 that plays anywhere. The video is converted in your browser and stays on your device.

Your file never leaves your device. Nothing is uploaded.

How it works

  1. Pick a file. Drag in a recording, a voice memo or a video. It opens in this tab; nothing is sent to a server.
  2. Choose the format. MP3 or M4A for small files that play anywhere, WAV or FLAC when you need lossless audio, OGG for the web. Set the quality if you like.
  3. Download it. Your browser converts the file and saves the result to your device. If you need a transcript, send the new file to the free Wave AI transcription tool in one click.

Common questions

What bitrate should I choose for AVI to MP3?

Older camera AVIs often carry uncompressed or low-bitrate audio. 128 kbps is plenty for speech and home videos, 192 kbps for music.

Is my AVI uploaded?

Nowhere. The converter runs inside your browser tab, so the file is read and converted on your own device and saved straight back to it. It is never uploaded to Wave or anyone else, and we never see its name or contents.

My AVI won't convert. Why?

A few very old AVIs use audio codecs the converter doesn't include, or were damaged in transfer. You'll see a message saying the file can't be read; re-exporting it from a video editor usually fixes it.

Can I transcribe an old video recording?

Yes. Convert it to MP3, then click "Transcribe this file for free" to send the audio to the free Wave AI transcription tool.
