Questions
Are my files uploaded?
Never. WEBM to MP4 conversion runs in your browser, so your files stay on your device.
Can I convert many at once?
Yes. Add as many as you like and download them all as one ZIP.
How long does it take?
Repackaging is quick. Re-encoding runs on your device and is slower for long videos; a computer is fastest.
