# Crop a Video to Any Aspect Ratio

Turn a landscape video into a vertical 9:16 clip, a square post or a 4:5 portrait, and slide the frame to keep the part that matters. Prefer to keep everything? Fit the whole picture on a blurred background instead.

## How to use it

1. Choose or drop a video.
2. Pick the aspect ratio: 9:16, 1:1, 4:5, 16:9 or 4:3.
3. Choose Crop (and slide the frame on the preview) or Fit on a blurred background.
4. Press Crop video, check the result, then download it or send it with a link.

## Which aspect ratio for what

| Ratio | Used for |
| --- | --- |
| 9:16 | TikTok, Reels, Shorts, Stories, WhatsApp status |
| 4:5 | Instagram and Facebook feed (takes the most screen space) |
| 1:1 | Square posts, profile videos |
| 16:9 | YouTube, TV, presentations |
| 4:3 | Older cameras, some slides |

## Crop, blur or bars

- **Crop to fill** cuts off the edges. The box on the preview shows exactly what stays; move it with the position slider.
- **Fit on blurred background** keeps the whole picture and fills the empty space with a blurred, darkened copy of the video.
- **Black bars** keeps the whole picture on black.

Cropping keeps the original pixels unless you pick a smaller output size, so a 4K video cropped to 9:16 stays sharp.

## Output and privacy

The result is an H.264 MP4, the format every app accepts; AAC sound is copied unchanged. Encoding runs in your browser with your device's video encoder, about real time on a phone. Nothing is uploaded. Presets for platforms: [Instagram](https://sharelargefilesfree.com/tools/resize-video-for-instagram) and [TikTok](https://sharelargefilesfree.com/tools/resize-video-for-tiktok).

## Frequently asked questions

### How do I crop a landscape video to vertical?

Choose 9:16, keep “Crop to fill”, and slide the position until the subject is inside the box on the preview.

### Can I keep the whole video instead of cutting the sides?

Yes. Choose “Fit on blurred background” or “Fit with black bars”.

### Does cropping reduce the quality?

The video is re-encoded at a high bitrate and keeps the original pixel density unless you choose a smaller size.

### Does it work with iPhone videos?

Yes. H.264 videos work in every current browser; HEVC works in Safari and in Chrome or Edge on Windows and macOS.

### Is my video uploaded?

No. It is cropped on your device.
