Crop

Good to know

• Drag anywhere on the picture to draw a region, and drag inside the region to move it. The four boxes hold the same region in pixels of the original, so a crop that has to be exact can be typed rather than aimed at.
• A shape locks the proportions while you drag: pick 1:1 for a profile picture or 16:9 for a cover, and the region keeps that ratio however you pull it. Switching shape reshapes the region you already have.
• The crop is taken at full resolution, not at the size shown on screen. What you see is scaled to fit the page; the region is held in the picture's own pixels, so nothing is lost to the preview.
• The picture is drawn the way its orientation tag says, so a photo taken sideways is cropped upright rather than on its side. Everything happens in your browser — the image is not uploaded anywhere.
