Cut a video down to what matters
Whether you’re clipping the highlight from a long recording, trimming dead air off the start, or grabbing a short section to share, Mynify lets you cut a video to an exact start and end time — right in your browser, with nothing uploaded.
Fast and lossless
Trimming with Mynify copies the selected span without re-encoding, so it’s quick even on large files and there’s no quality loss — the trimmed clip is identical to the original within the cut. Because it works this way, cuts land on the nearest keyframe, so the start point may snap by a fraction of a second. That’s normal (and unavoidable) for lossless trimming, and keeps the result instant and pristine.
How it works
- Drop your video.
- Enter a start and end time in seconds (e.g. start 5, end 20 for a 15-second clip).
- Mynify loads its engine once (~30MB, cached), then trims.
- Download the trimmed clip in the same format.
Tips
- Note timestamps in your video player before you start.
- Want just the audio of that section? Trim first, then run MP4 to MP3.
