Extract MP3 from AVI in three steps

Keep MP3, set quality
Choose a bitrate and hit Convert. The audio is extracted in your browser.

Save your audio
Each AVI becomes an MP3 to download, or grab them all as a Zip.

Why convert AVI to MP3
AVI is one of the oldest video containers — common on Windows for years, but inefficient and increasingly unsupported on modern devices. If all you want from an AVI is the audio, converting to MP3 drops the heavy video and gives you a small, universal sound file. It runs in your browser, so your footage is never uploaded.

Frequently asked questions
Can I get just the audio from an AVI?
Yes — the converter extracts the audio track and saves it as MP3.
Does extracting the AVI audio lose quality?
The audio is re-encoded once to MP3; at higher bitrates the difference is inaudible.
Does the AVI leave my computer?
No — the file is processed entirely in your browser.
How big an AVI can I convert?
Up to roughly 1 GB per file — browser conversion holds the video in memory.
Can I convert several AVI files in one go?
Yes — add the whole batch and download the MP3s together as a Zip.
Can I transcribe the AVI soundtrack?
Yes. Convert it to MP3 first, then SlayScribe turns the speech into text.
Need the words, not just the audio?
SlayScribe turns any audio or video into accurate text in seconds — transcripts, captions, and subtitles in 99 languages.
