Steps
Open the home page and find the Frame your image panel. Pick a crop ratio from the menu. Choose an image or drop one on the panel. Drag the frame over the part you want to keep, or focus it and press the arrow keys. Pick PNG or JPEG and press Download crop.
Crop or resize
Cropping removes edges to reach a new shape; resizing keeps the shape and changes the size. If the original and target ratios already match, resize. If they differ, crop instead of stretching the picture.
Worked example
A 1600 × 900 photo cropped to 4:3 keeps a 1200 × 900 section. A centered crop removes 200 pixels from each side, so move the frame toward the subject if it sits off-center.
