Do you upload my video?
No. The trimming pipeline runs locally in your browser.
Trim Video Online
Cut clips by timecode and export a new file. Copy the original media when the container and codec allow it — lossless and near-instant; transcode only when they do not.
Frequently asked questions
Why is trimming sometimes slower?
Most common formats can be copied in place, which is near-instant. Transcoding only happens when the container or codec cannot be copied, and that is slower.
Will trimming reduce quality?
Copying keeps the original quality. Transcoding may change quality depending on the browser encoder.
Which browsers are supported?
For best results, use the latest Chrome / Edge with WebCodecs support.
Can I trim long videos?
Yes, but processing time depends on your device and whether a transcode is required.
Which formats are supported?
Common inputs include MP4/WebM/MOV/MKV. Output supports MP4/WebM/MOV/MKV.
