WebM output
This browser-only trimmer re-records the selected range as WebM. It does not create a lossless MP4 cut.
Upload a browser-supported MP4, WebM, MOV, or M4V file, preview the video, then choose the start and end time for the clip you want.
You can type exact timestamps or use the preview video and the quick buttons to set the start and end from the current playback position.
This tool records the selected range into a new WebM file. It does not rewrite the original MP4, MOV, or WebM container without re-encoding.
For fast social previews, bug report clips, lightweight demos, and web assets, WebM is usually a practical browser-native output format.
The clip is decoded, trimmed, and recorded locally in your browser with video, canvas, and MediaRecorder APIs.
Your video is not uploaded or stored by this tool, and the generated download is created from a local object URL.
The output is useful when you need to share only the important moment from a longer clip without sending the whole source file.
No. The video trimmer runs locally in your browser. Your source video is not uploaded or stored by this tool.
Browsers can record canvas video as WebM through MediaRecorder. MP4 trimming usually needs server-side FFmpeg or a heavier WebAssembly encoder.
No. This browser-only version re-records the selected range, so it is practical and private but not a lossless container-level cut.
For reliable browser performance, keep the selected range under one minute. Shorter clips trim faster and produce smaller downloads.
