Question 1

How do I trim a video online?

Accepted Answer

Upload your video file (MP4, WebM, MOV), set the start and end times using the sliders or input fields, preview the trimmed section, and click Download.

Question 2

Is my video uploaded to a server?

Accepted Answer

No. All processing happens entirely in your browser using canvas recording. Your video files never leave your device.

Question 3

What video formats are supported?

Accepted Answer

The tool supports MP4, WebM, MOV, AVI and any format your browser can play. Output is saved as WebM (VP9 + Opus) for broad compatibility.

Does trimming reduce video quality?

The tool re-encodes the trimmed portion using high-quality WebM (VP9). There may be minimal quality difference, but the result is suitable for most uses.
