Frequently asked questions
Can I crop to an exact aspect ratio like 16:9 or 1:1, not just freehand?+
Yes. Pick one of the preset ratios (1:1, 4:3, 16:9, 3:4, or 9:16) before or after drawing your selection, and the crop box snaps to it. "Free" lets you drag any rectangle.
Does cropping shrink or compress my image?+
No. The crop is drawn from the original full-resolution image data, not from the resized preview, so the exported PNG keeps the source resolution for whatever area you selected.
Is the image uploaded anywhere to be cropped?+
No. The crop happens on an HTML canvas in your browser. The image never leaves your device, which matters if you're cropping something like a screenshot with personal details in it.
