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?
Use the quality slider to balance bitrate and file size.
