About the formats
FLAC, compressed lossless audio
FLAC compresses audio without losing anything: it plays back exactly like the original.
Strengths: Ideal for archiving music at CD quality or better in about half the size of a WAV.
Limits: It weighs several times more than an MP3 and some simple devices do not play it.

Frequently asked questions
Is my AVI uploaded to a server to turn it into FLAC?
No. The AVI to FLAC conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.
Can I extract only part of the AVI audio?
Yes: in the options set the start and end time, for example from 1:30 to 2:45, and only that clip is extracted.
Is there a size limit?
Up to 2 GB and 3 hours of video on desktop; on mobile, 500 MB and 30 minutes (AVI: 1 GB and 1 hour on desktop). If it is over, you are told before it starts and can trim it.
Can I convert several AVI files at once?
Yes. Drop as many AVI files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each FLAC or all of them in a ZIP.
