F4V to FLAC Converter

Convert F4V files to FLAC. Free, without uploading.

This tool converts F4V files to FLAC. Flash MP4 video.

FLAC is lossless compressed audio: about half the size of WAV with no quality loss. Only the audio of the F4V video is kept and saved as FLAC; the picture is dropped. FLAC is lossless, so the audio keeps the quality it has in the F4V 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 F4V 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.
