How it works

Your video is processed by your own computer and saved back to it. It is never uploaded.

Nothing leaves your device

The video is read straight from your disk, a little at a time, so even a file of several gigabytes works. The result is saved back to your computer as a normal download.

The size you asked for

When you pick an exact size, the tool checks the finished file before you download it. If it cannot get under your size, it tells you instead of handing you a file that will be rejected.

Phone videos look right

iPhones and many Android phones record HDR video, which looks grey and washed out on ordinary screens after most conversions. The tool adjusts the colours so the result looks right everywhere.

Check it yourself

Load the page, then switch off your internet and compress a video. For most videos it keeps working, because nothing needs to leave your computer.
