# Crop a Video to a Square

Square video fills more of a phone screen in a feed than landscape and shows in full in grids and profile previews. Choose which part to keep, or fit the whole picture on a blurred square.

**Quick answer:** To crop a video to square, open it here, move the crop box to the part you want to keep and press Make it square: you get a 1080 × 1080 MP4. Choose Fit on blurred background instead to keep the whole picture. It runs in your browser; nothing is uploaded.

## How to use it

1. Choose a landscape or vertical video.
2. Keep Crop to fill and slide the crop position until the subject is inside the square, watching the preview.
3. Or pick Fit on blurred background or black bars to keep the whole frame.
4. Press Make it square and download the 1080 × 1080 MP4.

## Crop or fit?

- **Crop to fill** cuts off the sides of a landscape video (or the top and bottom of a vertical one). The subject gets bigger, but anything near the edges is lost. Use the slider to pick the part to keep.
- **Fit on blurred background** keeps the whole picture and fills the rest of the square with a blurred, enlarged copy, the look many apps use.
- **Fit with black bars** keeps the whole picture with plain bars, like a letterboxed film.

## Where square video works best

Square 1:1 is supported by Instagram, Facebook, LinkedIn and X posts, shows fully in profile grids, and suits product clips and talking-head videos that sit in the middle of the frame. For Instagram the tall 4:5 shape takes even more of the screen: see [Resize video for Instagram](https://sharelargefilesfree.com/tools/resize-video-for-instagram). For Reels, TikTok and Shorts use 9:16 with [Resize video for TikTok](https://sharelargefilesfree.com/tools/resize-video-for-tiktok).

## Quality and sound

Cropping changes the picture, so the video is re-encoded as an H.264 MP4 at 1080 × 1080 (choose Keep the original pixels under Output size to keep the video's own resolution). AAC sound is copied unchanged. All of this runs on your device with your browser's video engine.

## Frequently asked questions

### What size is a square video?

1080 × 1080 pixels is the usual size for social media and what this page makes by default.

### Can I choose which part of the video stays?

Yes. Move the crop position slider; the preview shows the square on the video.

### How do I make a video square without cropping?

Choose Fit on blurred background or Fit with black bars. The whole picture stays visible inside the square.

### Does the crop follow a moving subject?

No. The crop box stays in one place for the whole clip, so pick a position that works throughout, or trim the video into parts.
