How to use

Pick an image, then drag the highlighted selection to choose the area you want to keep. The shaded region around your selection is dimmed, so it's easy to see the final crop. When you're happy, tap the button to download the cropped image as a JPG.

Cropping is useful for removing distracting edges, focusing the subject, or producing perfect square avatars from a rectangular photo. The whole process happens locally in your browser.
