What is Facebook Cover Resizer?

Facebook Cover Resizer crops and scales your images to the exact dimensions required for Facebook cover photos (820x312 for desktop, 640x360 for mobile). Preview how your cover will look on both desktop and mobile before downloading.

Facebook serves two cover crops: 820 × 312 for desktop and 640 × 360 for mobile. The tool lets you reposition the image by dragging until the part you care about sits inside both safe zones, with the profile-picture mockup pinned to the left so faces don't get covered. Export is a JPEG at quality 92 sized exactly to spec.

How to use

1. Upload any image you want to use as your Facebook cover photo.
2. Position and adjust the crop area to frame the most important part of your image.
3. Download your resized cover image, ready for Facebook.

When to use

• Refreshing your personal profile after a holiday and you have one wide landscape shot to fit both layouts.
• Setting up a new Facebook Page for a small business and you only have a square logo to adapt.
• Promoting a one-off event and you need a banner that won't crop the date out on mobile.

Result

Resize a 4000x3000 vacation photo to 820x312 pixels, centering the beach sunset so it stays in frame on your Facebook profile.

FAQ

What's the actual size Facebook expects for a cover photo?

Facebook displays the cover at 820 × 312 pixels on desktop and 640 × 360 on mobile. The same file is reused for both layouts, so any cropping difference comes from how the platform cuts the image to fit each viewport.

Why is there a pink safe zone in the preview?

The pink rectangle marks pixels that get clipped when the other layout displays your cover. Keep the headline, faces, and logos out of pink and they'll stay visible on both desktop and mobile.

Does the profile-picture mockup matter?

The profile photo sits over the bottom-left of the cover on every device. The circle in the preview shows you exactly where, so you can shift important content right or up and avoid burying it under the avatar.

Why does Facebook still compress my cover after I upload it?

Facebook re-encodes every cover photo on upload to save bandwidth. Starting from a clean JPEG at 820 × 312 at quality 92 minimises the recompression artefacts compared to uploading a huge 4K original.

Can I use this for Facebook Group covers or event covers too?

Yes. Pick the preset you need from the tabs: Desktop Cover (820 × 312), Mobile Cover (640 × 360), Group Cover (1640 × 856), Event Banner (1920 × 1005), Ad Image (1200 × 628), or Post Image (1200 × 630). Each one resizes to the exact pixels Facebook expects for that placement.
