Trim a Video Clip

Choose a start and an end, with sound if needed. Trimming is done by a real video engine (ffmpeg), in your browser.

Drop a video here or click to choose it. MP4, WebM, MOV depending on your browser.

Trim a Video is a free tool that runs entirely in your browser, with no data ever sent to a server. Keep a precise clip, with or without the sound.

How trimming works

This tool bundles a real video engine: ffmpeg, compiled to WebAssembly, running entirely in your browser. The video is genuinely decoded and re-encoded between the two chosen bounds, giving a precise trim instead of a real-time recording. The engine (about 30 MB) downloads once and then stays cached.

Keeping the sound or not

Unchecking "Keep the sound" drops the audio track from the resulting file, making it slightly lighter.

What this tool does not do

This tool only reads video formats your browser can already decode on screen (for the preview). The result is always produced in MP4 format, whatever the original format.

Frequently asked questions

What format do I get?

An MP4 file (H.264/AAC), natively played everywhere: browsers, phones, desktop players.

Can I trim several clips from the same video?

Yes, by re-running the operation with new bounds after each download, without reloading the page.

Are my files sent to a server?

No: processing happens entirely in your browser, on your device. No file is ever transmitted to a server, at any point.
