Online Video Trimmer When To Use
Online Video Trimmer is worth opening when you need a quick, one-off run without installing anything. This page covers when that fits and when it does not.
When it fits
Use it when you have a clip that only needs its start or end trimmed and you want the result in the same format and quality as the original. Trimming does not re-encode - it runs in FFmpeg's stream-copy mode, so the original resolution, bitrate, and codec are kept exactly as they were.
What to expect
Expect the trimmed clip to download in the same container format as the original, with identical resolution and bitrate. The file is processed in this browser tab (FFmpeg runs as a WebAssembly module loaded once per session) and is never uploaded to a server.
For converting the trimmed clip to a different format instead, see the related-tools section.
