About the Facebook Cover Photo Resizer

A Facebook cover photo displays at 820×312 pixels on desktop and 640×360 on mobile, so it is cropped differently across devices. This tool scales your image to fill the 820×312 desktop cover and center-crops the overflow so nothing is stretched. Keep the most important content centered so it survives both the desktop and mobile crops, and remember your profile photo overlaps the lower-left on desktop.
