Resize images to 820×312 (Facebook Cover)

The 820×312 resolution is the standard size for Facebook cover photos on desktop. It uses a wide banner format designed to sit at the top of your profile or page.

However, unlike most image sizes, Facebook covers behave differently across devices. What looks correct on desktop may appear cropped or shifted on mobile.

Resizing your image to 820×312 ensures a solid starting point, but proper composition is just as important as the dimensions.

This tool allows you to resize images to exact 820×312 dimensions while maintaining composition and visual clarity.

Everything runs locally in your browser, so your images stay private and processing remains fast.


Why 820×312 is tricky (desktop vs mobile)

Facebook cover images are displayed differently depending on the device.

  • Desktop: shows the full 820×312 width
  • Mobile: crops the sides and focuses on the center

This means that simply resizing an image is not enough — you also need to design for multiple viewports.

Safe area for Facebook covers

Because of mobile cropping, the center of the image is the safest area.

Think of the layout like this:

  • Left and right edges → may be cropped on mobile
  • Center area → always visible
  • Bottom-left → partially covered by profile picture

To avoid issues:

  • keep important text and logos in the center
  • avoid placing key elements near edges
  • leave breathing space around content

Composition tips for 820×312 images

Design for multiple devices

Always assume your image will be viewed on both desktop and mobile.

Center your key message

Important content should stay within the middle area of the image.

Avoid edge-dependent layouts

Designs that rely on full-width placement may break on mobile.

Use bold, simple visuals

Covers are often viewed quickly, so clarity is more important than detail.


Why your Facebook cover might look wrong

Common issues include:

  • important elements cut off on mobile
  • profile picture overlapping content
  • incorrect aspect ratio
  • text placed too close to edges

Using the correct size and designing with safe areas in mind solves most of these problems.
