Why does Illustrator cut graphics when exporting?

Question

JPEG

Has anyone encountered the problem that when exporting a graphic from Illustrator, it cuts off the rounded edges for some reason?
Example, I want to save a 72x72 px circle joxi.ru/8AnGgEZUjwlZWr , I make a 72x72px artboard... save.
The final picture is cut off for some reason joxi.ru/MAjG8EWU4w56yr ...
How to deal with this?
When saving a similar circle from Photoshop, everything turns out clearly joxi.ru/Grqz0j3IQwaoEm

Answer 1

In both final images (from the chandelier and photoshop), the circle has cropped edges. This comes from anti-aliasing - the appearance of light pixels along a curved line to visually simulate the smooth edge of a circle (otherwise there will be a pixel ladder).
There is only one treatment - either increase the artboard by one pixel from each edge, or reduce the circle by 1 pixel in radius.
