Frequently asked questions

Does it upload my video?

No — everything runs locally in your browser using an on-device video engine, so your file never leaves your device.

Will it lose quality?

Hitting a smaller size means a lower bitrate, so there is some trade-off. We pick the highest bitrate that still fits your target, so it looks as good as possible at that size.

Why is the first run slower?

The first compression downloads the ~30 MB video engine, which is then cached for instant use afterwards.
