FAQ
Are my videos uploaded?
No. Compression runs in your browser with ffmpeg.wasm. Your video never leaves your device.
Is there a watermark?
No watermark, ever.
Why is the first run slow?
It downloads the ~30MB video engine once, then caches it. Large videos still take time because all the work happens on your device.
What formats are supported?
MP4, MOV, WebM, and most common video formats. Output is MP4 (H.264).
