Which aspect ratios are built in?

Free-form, square, 4:3, 3:4, 16:9, 9:16 and 3:2 — plus a draggable crop box for exact regions.

Does cropping lose quality?

No — the kept region is copied at full resolution, pixel for pixel. Only the export format's own compression applies.

No — cropping happens on a canvas in your browser.

Crop an image to square, 16:9, 4:3 or any hand-drawn region with a visual crop box and live preview — processed on your device.
