HELP
HOW THIS WORKS
Your MP4 plays in the browser, then we record the stream to WebM.
This is a best-effort method (not full ffmpeg).
No uploads • runs locally on your device.
STEPS
1) Load an MP4
2) Press START (it records playback)
3) Press STOP (or wait to end)
4) Download the WebM
ESC returns to PAGE 1
IF IT FAILS
Try a different MIME option (VP8/VP9).
Some browsers don’t support captureStream or WebM recording.
On iOS Safari, this often won’t work.
QUALITY NOTES
This re-encodes; quality depends on device encoder.
Audio may be muted if device blocks capture audio.
For reliable conversion use desktop software.
