How to do it, step by step
- Choose the video (or audio).
- Drag the start and end handles, or type the seconds.
- Check the clip in the player.
- Under Export, choose format, size and quality and click Export video.
When this is useful
Remove the start and end of a recording
Keep only the part that matters.
Reduce a long video to a clip
Useful to send just the right moment.
Trim a clip from an audio file
The tool also accepts audio files.
Tips for a good result
- The app shows the final duration beside the original duration.
- To trim without rebuilding the video and with times in hh:mm:ss, also see WebFaz Video Converter.
- To cut several pieces of the same video, use the full editor (the S key splits the clip).
What this tool does not do
- It keeps a single continuous clip: it does not remove a piece from the middle.
- Everything happens in the browser: the video is not sent. Large files depend on the device’s memory and capacity.
- The video is rebuilt on export (it is not a direct copy): choose the quality and size under Export.
- MP4 depends on the browser having an H.264 encoder; without it, the app records in real time (it takes as long as the video, with the tab open).
- This page does only this task. Timeline, texts, effects and animations are in the full editor.
Frequently asked questions
- Does it lose quality when trimming?
- The video is rebuilt on export, so it depends on the chosen quality: at Maximum the difference is as small as possible, but the file is not an exact copy of the original.
- Which formats go in?
- MP4, MOV, WebM, MKV, M4V and TS, as well as audio.
- What is the file name?
- The downloaded file is called webfaz-corte, with the .mp4 or .webm extension.
