How to Crop an Image to the Right Size

What does cropping do?

Cropping removes areas from the edges of an image so the remaining picture has a different composition or shape. Unlike resizing, it does not simply scale every part of the original.

Cropping is useful for removing distractions, centring a subject or fitting an image into a required aspect ratio.

Crop for composition

Before worrying about exact dimensions, decide what the image needs to show. Keep important faces, text and objects away from edges that may be cut off.

A tighter crop can make a subject more prominent, while too much cropping can remove useful context.

Understanding aspect ratio

Aspect ratio describes the shape of the crop. A 1:1 ratio is square, 16:9 is wide and ratios such as 4:5 are more portrait-shaped.

If a website or social platform specifies a ratio, cropping to that shape first prevents unexpected automatic trimming later.

Crop first, resize second

If you need both a particular shape and a particular pixel size, it is usually clearer to choose the crop area first and then resize the finished crop.

For example, crop a photo to a square composition, then resize that square to 1000 × 1000 pixels.

Use a visual crop tool

The Image Cropper lets you position the crop visually rather than guessing coordinates. Preview the result and make sure the important content remains inside the selected area.

Keep the uncropped original if you may need a different composition later.
