About Crop Image
Crop images to preset aspect ratios (1:1, 4:3, 16:9, 9:16, 3:2, A4) or freeform, with optional 90° rotation steps.
Choose a preset aspect ratio (1:1, 4:3, 16:9, 9:16, 3:2, A4) or freeform. The crop box centers on the image; drag to reposition (in the interactive version). Rotate in 90° increments before cropping. Output as PNG, JPEG, or WebP.
All processing is local via Canvas — no uploads. The static preview shows the centered crop; the interactive page lets you drag the crop box.
