AVI (an older, widely seen video format) and MP3 (the universal lossy audio format). This free tool converts AVI to MP3 directly in your browser, so your file never leaves your device. No install and no sign-up needed.
Batch conversion, ZIP download and quality control
- Convert many files at once — drop or pick several AVI files and they are converted one after another.
- When you convert two or more files, the results are bundled into a single ZIP so you download everything in one click.
- Adjust quality and size: lower the quality or resize to make the MP3 files smaller. The setting applies to every file in the batch.
How to convert AVI to MP3
- 1Drop your AVI file onto the box above, or click to choose it.

- 3Click "Convert to MP3" and wait a moment.
- 4Download the MP3 file — it is saved straight to your device.
Common uses
- Make a AVI clip play everywhere by converting it to MP3.
- Meet a social upload requirement, extract the audio or make a short GIF.
- Reduce file size while keeping a MP3 version that plays smoothly.
Quality & compatibility notes
- Both AVI and MP3 are lossy formats, so re-encoding may slightly reduce quality.
- This extracts the audio track and discards the video.
- Everything runs in your browser — your file is never uploaded.
Frequently asked questions
Is my AVI file uploaded when I convert it to MP3?＋
No. The conversion runs entirely in your browser using your device, so your file is never sent to any server.
Will the quality drop when I convert AVI to MP3?＋
Both AVI and MP3 are lossy formats, so re-encoding may slightly reduce quality.
Can I convert several AVI files to MP3 at once?＋
Yes. Add multiple files and they are converted one by one in your browser. A single file downloads directly; two or more are packed into one ZIP. If one file fails, the others still convert.
Is it free? Do I need to sign up?＋
Yes, it is completely free — no sign-up, no install and no watermark.
Is there a file size limit?＋
You can convert files up to 200 MB. Everything is processed on your device, so very large files depend on your available memory.
Can I convert the other way, from MP3 back to AVI?＋
That direction is not available right now. AVI can still be converted to several other formats.
