Website is downloading 1 pixel less than selected dimension

[Copperplate]

Hello, firstly thank you for this amazing site. Today I discovered that for some reason, all icons are downloading 1 pixel less than the selected power of 2 dimension. Example: Select the plain circle icon, and choose 512. It will download as 511x511. Choose 256, and it will download as 255x255. Thank you for looking into this.

Update: I clicked the preset size buttons a few times, refreshed the page, then clicked them again and tried downloading and now it works! Not sure what caused that bug, but at least it was not permanent. :-)

SOLVED: The unusual download size is DIRECTLY connected to your zoom level in Google Chrome (ie. if you set your dimensions to 512 x 512, but your browser's zoom setting is at 150%, the icon will download as 768 x 768), so always be sure to download with a browser zoom of 1. :-)
