Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed entirely inside your browser. Your files never leave your device or get sent anywhere.
How much smaller will my video get?
Typically 40–80% smaller depending on the preset and the original file. Screen recordings and phone videos compress especially well.
Will the quality drop?
The High preset is visually near-identical. Balanced is ideal for sharing. Smallest is for chat apps and email limits, where some softness is acceptable.
Why does it take a while?
The video is re-encoded entirely in your browser (that's what keeps it private). Expect roughly real-time speed — a 5-minute video takes a few minutes.
