Frequently asked questions

Is the video compressor really free?
Yes. It is completely free with no signup, no watermarks, and no limits.
Are my videos uploaded anywhere?
No. Compression happens 100% inside your browser, so your videos never leave your device. This also means it stays fast even on slow connections.
Which video formats are supported?
MP4, WebM, and MOV files are supported.
How much smaller will my video get?
The High preset shrinks files by about 35%, Medium by about 60%, and Small by about 78%. Results vary with the source video.
What does the custom bitrate option do?
It lets you set an exact bitrate, such as 1200 kbps, instead of using one of the presets. Lower bitrates mean smaller files and slightly softer quality.
Should I lower the resolution too?
If file size matters more than sharpness, capping at 720p (HD) is the recommended middle ground, and 480p gives the smallest files.
Does it work on mobile?
Yes. The compressor works in modern mobile browsers on Android and iOS, as well as on desktop.
Why does it say to keep the tab open?
Compression runs locally on your device in real time, so closing the tab or navigating away stops the process.
