What is this tool?

Facebook Cover Photo Resizer prepares wide header images for Facebook pages and profiles. Cover photos are displayed across a large horizontal space, but they can be cropped differently on desktop and mobile. A clean cover image should keep important text, faces, and logos away from the extreme edges.

Use this tool for business pages, creator pages, event announcements, community groups, seasonal banners, and profile headers. The 851x315 preset is a common cover-photo target, but the most important part is designing a safe central area that still looks good when cropped.

Cover photos often contain branding or calls to action, but too much text can feel cluttered and may be hard to read on phones. Use strong imagery, simple text, and enough spacing around the main subject.
