Resize Image for Facebook Cover — Free 820×312 Resizer
A Facebook cover looks great on your screen and broken on everyone else’s — because desktop and mobile crop it differently, and your profile picture covers the bottom-left corner. This tool resizes any photo to the exact desktop cover size of 820×312 and shows safe-zone guides for the profile-picture overlap and the mobile side-crop, so your cover looks right everywhere. All in your browser; your photos never leave your device.

How it works
- Step 1 — Drop in your photo or branded graphic.
- Step 2 — Choose Cover (center-crop to fill) or Contain (blur-pad). The safe-zone guides show where your profile picture overlaps the bottom-left and where mobile crops ~90px off each side — keep logos and text clear of both.
- Step 3 — Download an 820×312 image — Facebook’s exact desktop cover size. Guides are preview-only; your download is clean.

Frequently asked questions
Why 820×312? That’s the size Facebook renders page covers at on desktop. Mobile shows a cropped 640×360 window — which is why the side-crop guides matter: anything in the outer 90px on each side vanishes on phones.
Where does my profile picture sit? Overlapping the bottom-left of the cover — the amber circle in the preview marks the overlap zone. Keep text and faces out of it.
Are my photos private? Yes. Everything runs locally in your browser. Your files never leave your browser, and nothing is uploaded anywhere.
