When it comes in handy

For example, it helps when you need to turn a horizontal clip into a 9:16 vertical frame for Instagram Reels or YouTube Shorts.

It's also useful for cutting off an unwanted area or watermark on one side of the frame.

Easy with aspect presets

Pick a 1:1 (square), 16:9 (landscape), or 9:16 (portrait) preset and the region snaps to that ratio, so you can make platform-ready clips easily.

Frequently asked questions

Is the video uploaded to a server?+

No. Cropping runs inside your browser, so the video never leaves your device.

Can I make a vertical video?+

Yes. Use the 9:16 preset to crop to a vertical frame that fits Shorts and Reels.

Does quality drop?+

Cropping re-encodes, so there can be a slight change. Keep quality high to stay close to the original.
