FAQ
How much can it reduce the file size?
Depending on the original encoding and your quality setting, reductions of 50–90% are typical. Lower quality and resolution settings produce smaller files.
Is my video uploaded to a server?
No. All processing is done locally in your browser using the Canvas API and MediaRecorder. Your video never leaves your device.
What format is the output?
The compressed video is exported as WebM (VP9 codec), which is supported by all modern browsers and most video players.
Is there a file size limit?
There's no hard limit, but very large files (500MB+) may slow down your browser. We recommend files under 200 MB for the best experience.
