Cut a video down to just the part you want by setting a start and end point. The trimmed range is saved as a standard MP4 with no quality loss and no watermark, and it finishes almost instantly.

Set the range two ways

There are two ways to mark your cut: drag the two handles along the timeline for a quick visual selection, or type exact From and To times when you already know them to the second. Typing is the reliable route for matching a script cue or a beat you spotted while scrubbing; the handles are better for eyeballing where a clip starts breathing or where dead air begins. Switch between them freely, rough in the selection with a handle, then fine-tune the numbers.

Why the start can shift a little

Because the kept range is copied rather than rebuilt, the cut has to begin on a keyframe, a self-contained reference frame the video stores every few seconds. Your chosen start snaps back to the nearest one, so playback can begin a fraction of a second before the exact time you typed. The upside is that the picture is clean from the first frame and the trim finishes almost instantly. If a precise opening matters, set your start slightly ahead of the moment you actually want.

Trimming to fit an upload limit

A shorter clip is a smaller file, so trimming is the quickest way to slip under an upload cap without degrading anything. Real limits worth knowing: Gmail attaches up to 25 MB, a free Discord account allows 10 MB per file, and WhatsApp caps shared video at 16 MB. Cutting to just the essential seconds often gets you under these. A standard X (Twitter) post takes video up to 2 minutes 20 seconds. Trimming changes duration and file size only; it won't change the shape, so a 9:16 vertical clip stays 9:16.

Tips

  • Type times into the From/To fields when matching a transcript or a musical beat, it's faster and steadier than nudging handles pixel by pixel.
  • Leave about half a second of padding before your intended start, since the cut snaps to the nearest keyframe and can land just before it.
  • Check the frame sitting under your From handle before saving, that exact frame is what viewers see first.
  • To pull several clips from one recording, trim and save, then reopen the original and set a new range.

Questions

Will trimming lower my video's quality?
No. The range you keep is copied out untouched, so it looks identical to the source, and there's no watermark added.
Why does my clip start a moment before the time I set?
The start lands on the nearest keyframe, a reference frame stored every few seconds, so it can snap slightly earlier than the exact time you typed. Set your start a touch ahead of the moment to avoid losing anything you want.
Can I remove a section from the middle of a video?
This tool keeps one continuous range from your start to your end point. To drop a middle section, trim the part before it and the part after it as two separate exports.
Are my files uploaded anywhere?
No. Everything happens on your own device, nothing is sent to a server, and no account is needed. It's free to use.
