A video often has more in the frame than you want. There is empty space around the subject, a sliver of the wrong room down one edge, or a wide landscape shot that needs to become a tall clip for a phone feed. Cropping fixes all of these by keeping the part of the frame you want and dropping the rest.

The short version: load the video, pick a crop shape or set a custom size, and download the result. The video cropper does it on your device, with no watermark and nothing uploaded.

Cropping is not the same as resizing

It helps to be clear on the difference, because the two get mixed up.

  • Cropping keeps a rectangle of the original frame and throws away everything outside it. The subject is unchanged; you simply see less around it.
  • Resizing keeps the whole frame but makes it smaller or larger, scaling every pixel.

Use cropping when you want to cut something out of shot or change the shape of the frame. Use resizing when you want the same picture at a different size.

Crop for the platform you are posting to

Most cropping is about shape. Each platform favours a frame, and matching it stops the app adding its own bars or awkward auto-crop.

  • Square (1:1) suits an Instagram feed post and many profile grids.
  • Portrait (9:16) is the full-height frame for Reels, TikTok and Stories.
  • Portrait (4:5) is a taller feed post that takes up more screen without going full height.
  • Landscape (16:9) is the standard wide frame for most players and for YouTube.

Pick the shape first, then position the frame so the subject sits where you want it.

How to crop a video

Step 1: Add your video

Drop in the clip you want to crop. The preview loads so you can see the full frame.

Step 2: Set the crop

Choose a square, portrait or landscape preset, or switch to a custom width and height. The frame is centred by default; move it if the subject is off to one side.

Step 3: Download the result

Crop, check the new frame in the preview, and save the clip. No watermark, no account, and nothing was uploaded.

Keep quality by cropping, not zooming

Because cropping keeps part of the original frame at its native detail, the area you keep looks exactly as sharp as it did before. There is no enlargement, so nothing goes soft. The only thing to watch is how much you remove: if you crop down to a small slice of a low-resolution clip, the result is a small video, simply because there are fewer pixels left. Crop from the highest-resolution version you have for the best outcome.

The short version

When a video has too much in the frame or the wrong shape for where it is going, crop it rather than living with the extra. Use a preset to match the platform, or a custom size for anything else, and the kept area stays at full detail. It all runs in your browser, so the clip stays on your device and comes back without a watermark. If you want the same picture at a smaller size instead, resize it.

Frequently asked questions

How do I crop a video to a square for Instagram?
Choose the square preset, which sets a 1:1 frame centred on the picture. Nudge it if the subject sits off to one side, then crop and download. The result is a square clip ready for a feed post or profile grid.
Can I crop a video to vertical for Reels or TikTok?
Yes. Pick the portrait preset for a tall 9:16 frame, or set a custom width and height for any shape. The part inside the frame keeps its full detail, and only the edges outside it are removed.
Does cropping zoom in or just cut the edges?
It cuts the edges. Cropping keeps a rectangle of the original frame and discards what is outside it, so the kept area stays at its native detail rather than being stretched or enlarged.
Is my video uploaded to crop it?
No. The crop runs on your own device in the browser, so the clip is never sent to a server and nothing is stored. Private footage stays private.
