Trim MP4 Video
Cut an MP4 down to the passage you want to keep. Set a start and an end, and the clip is exported as MP4 without re-encoding, so the quality is untouched and there is no watermark. The video stays on your device.

Most online video editors decode your file and compress it again when you export. That takes minutes, lowers the quality a little each time, and is the step where a watermark or a resolution cap is usually applied on free plans.
Copying the stream avoids all of that. The part you keep is taken out of the file exactly as it was recorded. A ten-minute 1080p video trimmed to thirty seconds is ready almost immediately, at the original bitrate.
Typical reasons to cut an MP4
Removing the seconds before and after the useful part of a phone recording or a screen capture is the most common one. Shortening a clip to fit a platform's length limit is the second, and extracting one passage from a long meeting or lecture is the third.
Trimming is also the most effective way to make a video lighter. A file's weight is proportional to its duration, so removing half the length removes half the megabytes with no loss, where compression would have to degrade the picture to save as much.
Frequently asked questions
No. Nothing is added to your video: no logo, no intro, no end card. The exported clip is your footage, shortened.
No. The selected part is copied as it is, without re-encoding. Picture and sound are identical to the original, and the export takes seconds even for long videos.
There is no limit set by the tool, since nothing is uploaded. The practical ceiling is your device's memory: very large files of several gigabytes may fail on a phone or an older computer.
A cut without re-encoding has to begin on a keyframe, which is a complete image stored every second or two in an MP4. The start snaps to the nearest one before your mark.
