Frequently Asked Questions

How precise is the trim point?

Frame-accurate — the tool re-encodes the selected range rather than cutting at the nearest keyframe, so your start and end points land exactly where you set them, down to a tenth of a second.

Is my video uploaded anywhere?

No. The video preview and the actual trim both happen entirely inside your browser, on your own device.

What's the video engine this runs on?

A real, self-hosted build of FFmpeg compiled to WebAssembly — about a 30MB one-time download the first time you use any video/audio tool on this site, then cached by your browser for every tool afterward.

Does trimming lose quality?

A small amount, since the selected range is re-encoded (the price of frame-accurate cuts) — at the same settings used here, the difference is not visually noticeable for typical clips.

Is this free?

Yes, completely free, with no daily limit.
