FAQ
Will my video be uploaded?
No. The compression happens entirely in your browser (using open-source ffmpeg), and your video is never sent to any server.
Why is it slow?
Browser-based encoding is limited by your device's performance, especially for longer videos. Lowering resolution or selecting "Save Space" can speed up processing and further reduce file size.
What formats are supported?
Supports common video formats like mp4/mov/mkv/avi/webm, outputting all as MP4 (H.264) for maximum compatibility.
