Video Crop

Crop a video to a region or a ratio preset — vertical 9:16, square, 16:9. No upload.

About this tool

Drag a box on a frame or pick a ratio preset (1:1, 9:16, 16:9, 4:5), then re-encode just that region. The crop is fixed for the whole clip. WebM out, nothing uploaded.

Reframing for vertical, and the fixed-crop trade

The most common reason to crop a video today is the platform mismatch: landscape footage that has to become a 9:16 vertical for Reels, Shorts and TikTok, or a square for a feed. A preset gives the largest centred box of that shape; drag it to the part of the frame that matters, or draw your own box for an arbitrary region — removing a watermark bar, a chat window, or the empty half of a screen recording. Honest scope: the crop stays in one place for the whole clip, which suits most talking-head, product and screen content; tracking a moving subject needs an editor. The output is re-recorded in real time on your device (browsers can't cut a file directly), so it takes as long as the clip plays, keeps the sound, and comes out as WebM; the MP4 converter follows where supported. Trim before cropping with the trimmer to save time, and compress after if size matters; the still-image version is the image cropper.

Frequently asked questions

Can I make a landscape video vertical?

Yes — pick 9:16, drag the box over the important part, and re-encode. That's the Reels/Shorts workflow.

Does the crop move with the subject?

No — it's fixed for the whole clip. Fine for most footage; for a subject moving across the frame you need a video editor with tracking.

Why does it take as long as the video?

The cropped picture is re-recorded in real time by the browser — the only on-device method without a server. Trim first to shorten the wait.

Is the video uploaded?

No — everything runs in your browser.
