# Crop video to any shape, without uploading it

Drag a rectangle over your video, locked to 9:16, 1:1, 4:5 or 16:9 or free, and keep only what's inside. MP4, MOV, WebM and more. Free, no sign-up.

Your file never leaves your device: the tool runs inside your browser. Up to 500 MB and 2 minutes. Use it at https://opusmotion.com/tools/crop-video.

## How to use it

1. Drop your video, or tap the box to pick it.
2. Pick a shape (9:16 for Reels, TikTok and Shorts, 1:1 or 4:5 for feed posts, 16:9 for YouTube, or Free) and drag the rectangle over the part you want. Pull a corner to resize it.
3. Tap Crop. The cropped video is encoded on your device, with its sound.
4. Download the MP4, or put the clip in a launch template.

The first time, your browser downloads the video engine (31 MB, once); after that it opens from the cache.

## Questions

### How do I crop a video?

Drop it, choose a shape, drag the rectangle over what you want to keep and tap Crop. Everything outside the rectangle is cut away, for the whole length of the video.

### How do I crop a video for Instagram, TikTok or YouTube?

Pick 9:16 for Reels, TikTok and Shorts, 1:1 or 4:5 for a feed post, or 16:9 for YouTube. The rectangle keeps that shape while you move and resize it.

### What's the difference between cropping and resizing?

Cropping cuts away the edges and keeps part of the picture. Resizing keeps the whole picture and adds a background around it to reach the new shape: for that, use the resize video tool.

### Does cropping lower the quality?

The part you keep stays at its own resolution, up to 1,920 pixels on the long side: it isn't stretched. A small crop of a video gives a small video, so keep the rectangle large enough for where it will play.

### How long can the video be?

Up to 2 minutes and 500 MB. On a phone or low-memory device: 1 minute and 200 MB. It's encoded on your device, so a long or 4K video takes a while, and longer on a phone.

### Is my video uploaded anywhere?

No. It's cropped inside your browser and never sent to a server. The first time, your browser downloads the video engine (31 MB, once); after that it opens from the cache.
