Frequently asked questions
Can I crop more than one image at a time?
No. The crop tool holds a single image, and a second file is refused with a message until you remove the current one.
Does cropping change the shape of what is left?
No. Cropping only removes the pixels outside the selection; everything inside keeps its original shape and detail.
How do I get an exact pixel size?
Choose the ratio that matches the destination and read the pixel value under the preview. The export uses exactly those pixels.
