Frequently Asked Questions

What's the maximum file size?

Browser memory is the only limit. Works fine up to ~500MB in Chrome.

Can I trim Zoom or Loom recordings?

Absolutely. Export the MP4/WebM first, then drag it in here.

How does the online trimmer work?

Our trimmer uses the MediaRecorder API to capture the portion of video you selected, then saves it as a new file. This all happens locally in your browser.

Which browsers work best?

Chrome, Edge, and Firefox provide the best performance and compatibility. Safari has some limitations with video processing in the browser.
