AVI to FLAC Converter

Convert AVI files to FLAC. Free, without uploading.

This tool converts AVI files to FLAC. AVI is Windows’ classic video container. Older players and some devices still want it; files are larger than with modern formats.

FLAC is lossless compressed audio: about half the size of WAV with no quality loss. Only the audio of the AVI video is kept and saved as FLAC; the picture is dropped. FLAC is lossless, so the audio keeps the quality it has in the AVI file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the AVI video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the FLAC file.

Is my file uploaded?
