What is an AVI file?
AVI – AVI video. AVI is Microsoft's old video container from 1992. Plenty of older cameras, players and editing programs still use it. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.
AVI Converter →What is an MP3 file?
MP3 – MP3 audio. MP3 is the most widely played audio format: music compressed to about a tenth of its size, which every phone, player and car stereo plays. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions
Is converting AVI to MP3 free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my AVI files uploaded anywhere?
This conversion runs on our server, because converting video needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the AVI file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the MP3 look the same as the AVI?
Only the sound is kept: the pictures are left out, and the MP3 is made from the first sound track.
Can I convert several AVI files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
