- Preview the new region and save the cropped copy.

About this conversion
Set the crop rectangle in pixels and export just that region. Preview the selection before making a new image.
The crop coordinates are measured from the upper-left corner of the decoded image. A crop outside the source bounds is rejected instead of silently stretching or clipping the file.
Limits to know
Each input is limited to 40 MiB and 16 megapixels so the browser has a safer memory budget. Very large dimensions can still exceed the memory available on a phone.
Processing runs in this browser. Originals are not overwritten, and the output size is measured in bytes before download. Keep a backup of important files.
03 / FAQ
Questions people ask
Can I crop outside the image?
