Frequently asked questions
How do centimetres and DPI relate?
Pixels = centimetres × DPI / 2.54. JPG and PNG store the selected DPI. WebP cannot store this value.
Does enlargement make an image sharper?
No. New pixels cannot restore missing detail. With aspect ratio locked, standard sizes fit the image inside the selected frame.
