How to trim a video online
Upload your video, set the start time and end time in seconds, and click Trim. The tool extracts the selected segment using FFmpeg's stream copy mode — meaning no re-encoding happens and the trim is instant at any bitrate.
For precise timing, play the video in a media player and note the timestamps you want, then enter them in the trim controls.
Trim before compressing
The most effective way to reduce video file size is to trim it shorter before compressing. A 30-second clip at 8MB looks dramatically better than a 5-minute clip at 8MB, because more bits can be allocated per frame.
Workflow: Trim → Mute (if no audio needed) → Compress to target size.
Frequently asked questions
Does trimming reduce video quality?
No. The tool uses FFmpeg stream copy mode, which cuts at the exact timestamp without re-encoding. There is zero quality loss during trimming.
Can I trim a video to the exact second?
Yes. Enter the start and end time in seconds (decimals accepted, e.g. 12.5 for 12 seconds and 500ms).
What formats can I trim?
MP4, MOV, WebM, AVI, MKV — any format your browser can read.
