What is MP3?
The most compatible audio format — plays anywhere.

Lossless compressed audio — smaller files with no quality loss.
FAQ
Are my files uploaded?
No. Conversion runs entirely inside your browser; your video and audio never reach any server.
Is it free?
Completely free. No account, no installation.
Can I convert long files?
Yes, but processing runs on your device, so long files can take a few minutes. The first conversion also downloads the engine (~31MB).
Can I choose the quality?
FLAC is lossless, so no quality setting is needed.
