Drag a box or type exact pixel coordinates
You define a rectangle on the image, then the tool cuts out exactly those pixels.
The crop box starts centred at 80% of the image. Drag it to move it, or use its corner and edge handles to resize. The Aspect Ratio buttons (Free, 1:1, 4:3, 16:9, 3:2) lock the proportion while you resize. Below the preview, X, Y, Width and Height accept exact values in original pixels, which is useful when you need the same crop rectangle repeated. The box cannot leave the image or shrink below 10 pixels.
