How to edit a video in your browser
Short answer
Common quick video edits — cutting, splitting, looping, muting, and replacing audio — can run entirely in the browser and export MP4. No upload or install is needed because the video is processed in the tab.
Small video jobs, no install
You often do not need a video editor — you need one small change: shorten a clip, mute it, loop it, or split it into parts. Modern browsers can do each of these locally, so the file stays on your device and you get an MP4 back.
The common edits
- Cut / trimKeep only the part you need by setting a start and end. The quickest way to shrink a clip and drop dead air.
- SplitBreak one long video into several MP4 parts — for chapters, uploads, or sharing sections separately.
- LoopRepeat a short clip a number of times into one longer MP4 — useful for backgrounds and social loops.
- Mute or swap audioRemove a video's audio track, or add your own music or voiceover in its place.
