Why is the picture 1 pixel larger than necessary when saving a png in Adobe illustrator?

Question

PNG

When saving 4 pictures (export for screens) by the size of the artboard, for some reason png is 1 pixel larger. Instead of the required 507*507, 508*508 is saved.
How to fix it? The png needs to have the exact dimensions of the artboard

Answer 1

This is not related to the size of the artboard itself, but to the coordinates of this artboard itself. If there is a shift by half a pixel, then wait for an extra pixel in the finished picture :)
