How the crop is calculated
The selection you drag is a rectangle in display pixels. On export it is divided by the display scale to recover the exact source rectangle, and that region is drawn into a new canvas at its native size. The result is never stretched or re-sampled twice — no quality is lost beyond the lossy JPG step if you choose JPG.
With a fixed ratio selected, the box keeps that shape while you resize from any corner, which is what you want for profile pictures, square thumbnails and widescreen headers.
FAQ
Does cropping reduce resolution?
The crop is exported at the source pixels of the selected region, so the pixels you keep are untouched. The image simply covers a smaller area.
Can I keep transparency?
Yes — export as PNG and transparent pixels stay transparent. JPG has no alpha channel, so transparent areas are flattened onto white.
Is my image uploaded?
No. Everything runs locally in your browser.
