Crop Image
Upload an image, adjust the crop area by dragging in the preview (or typing exact values), and download the result.

How it works
All processing happens locally, in your browser. Your image is never sent to any server, which keeps things more private and secure. Drag the rectangle to move the selection, or the four corners to resize it — the preview shows exactly the area that will be cropped. The X, Y, width, and height fields show (and let you adjust) the selection in the original image's pixels, for anyone who prefers typing exact values.
