Frequently Asked Questions

How much can I reduce the file size?

It depends on the source video. Screen recordings with static content can often be reduced by 50–80%. Videos with lots of motion see smaller reductions.

Will compression affect video quality?

At high quality, the difference is barely noticeable. Medium quality is a good balance for most uses. Low quality produces the smallest files but with visible quality loss.

What video formats are supported?

You can upload any format your browser can play — MP4, WebM, MOV, MKV, and more. Output is MP4 or WebM depending on your selection and browser support.

Is there a file size or duration limit?

There is no hard limit, but very large or long videos use more memory and take longer to process since everything runs locally in your browser.

Is my video uploaded to a server?

No. All compression happens entirely in your browser. Your video never leaves your device.
