How to crop an image

Drop in an image and pick a ratio preset, or Free for any shape. Drag the selection over the part you want to keep, or type the exact position and size in pixels. The output dimensions update as you drag. When you download, the crop is applied to the original full-resolution pixels, not to the preview on screen.

Which ratio to use

Square (1:1) fits Instagram feed posts and profile pictures. 16:9 is the shape of YouTube thumbnails, presentation slides, and most video. 4:3 matches classic slide decks and many tablet screenshots. 3:2 is the native shape of most camera sensors and of 4 by 6 inch prints. 9:16 is the vertical format used by Stories, Reels, TikTok, and phone wallpapers.

Cropping screenshots before you share them

Cropping is the quickest way to remove a browser toolbar, a notification bar, or a busy desktop around the window you care about. It is not a way to hide something in the middle of an image, though. To cover an email address, a name, or an API key that sits inside the area you keep, blur or pixelate it in the screenshot editor instead.

Frequently asked questions

Cropping is per-image, because the right selection depends on what is in each picture. To apply identical dimensions across a batch, use the resize tool instead.
