常見問題
Is video compression free?
Yes. Browser compression uses no credits and works for guests. Files stay on your device.
How is this different from image compression?
Video is encoded in this browser tab and is never uploaded. Image compression runs on the server, so it can take 20 photos at once.
Why do I sometimes see 0%?
If the result is not smaller, the original file is kept so the download never grows. Try Smallest mode.
