Trim and cut video

How it works

1. 1

   Add your video

   Drop, pick, or paste the video you want to cut down.

2. 2

   Set in and out points

   Drag the range on the timeline to the part you want to keep.

3. 3

   Trim and download

   Choose fast copy or precise, then download. No watermark.

Trimming is a cut, not a re-encode

A video is not a flat strip of frames. It is built from keyframes, which are complete pictures, followed by runs of frames that store only what changed since the last one. That structure is what makes video small, and it is also why cutting is less obvious than dragging a handle: a cut that lands between keyframes leaves the following frames describing changes to a picture that is no longer there.

So a trim either snaps to the nearest keyframe, which is instant because the frames can be copied through untouched, or it re-encodes the opening stretch so the cut lands exactly where you put it. This tool takes the second path when your in-point demands it, which is why a frame-accurate cut costs a little processing time while a keyframe-aligned one is nearly free.

Trimming is also the cheapest way to make a file smaller, and the only one that costs no quality at all. Half the duration is half the size, with every remaining frame untouched. Before you compress anything, cut the dead air at the front and the drift at the end, because those seconds are paid for in bitrate like any other.

Cut video online without uploading it first

Trimming is the most common reason people reach for an online editor, and it is the worst possible reason to hand a file to a stranger's server. The clip you want to cut down is usually the one you have not shared yet: the unedited take, the screen recording with a notification in it, the footage with a face or an address in frame.

Nothing here uploads. The timeline scrubs from the file on your disk, the cut is performed on your device, and the result downloads from your own machine, with no account, no watermark, and no limit on how long the source is. The parts you cut away never existed anywhere but in your browser's memory.

If you need several pieces out of one recording rather than one continuous cut, the splitter is the better tool, and it can chop a long video into fixed-length parts in a single pass. To join what you keep onto other footage afterwards, the merger will normalize the clips so they play as one.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

What is the difference between fast copy and precise?

Fast copy is instant and lossless but cuts at the nearest keyframe, so the start can shift slightly. Precise re-encodes for a frame-exact cut, which takes longer.

Does my video get uploaded?

No. Trimming happens in your browser; your file never leaves your device.

Is there a watermark or size limit?

No watermark and no artificial size cap. The only limit is your device's memory.

Can I trim without re-encoding?

Yes. Fast copy trims without re-encoding, so it is instant and keeps full quality.

• Video size and length limits for every platform

  Every platform enforces two limits, a size cap and a length cap, and most of them enforce a third one they never tell you about: the quality they will re-compress your video down to once it arrives. Here is what each one actually allows.

• How to compress a video without ruining it

  Compression is a negotiation between size and detail, and most people lose it by pulling the wrong lever. Understanding what the encoder is actually doing makes the difference between a clean small file and a blocky one.
