Facebook Cover Photo Size Guide

Facebook Cover Photo & Banner Size — 2026

The correct size for a Facebook Page cover photo is 820 × 312 pixels on desktop and renders as 640 × 360 pixels on mobile. Facebook crops the sides on mobile and the top/bottom on desktop, so keeping important content centered is critical. This tool converts any image to the exact 820×312 dimensions in one click — entirely in your browser.

Which Background Mode Should I Use?

  • Fill (crop to fit): The image is scaled up to cover the full 820×312 canvas, then centered and cropped. No bars appear — the cover is completely filled edge-to-edge. Ideal for landscape photos or branded banners where slight edge cropping is acceptable.
  • Blur Background: The full image is visible in the center while a blurred, darkened version fills the background. The most popular technique for adapting square or portrait images into a wide cover without cropping or white bars.
  • Fit (white bars): The entire image is visible inside the 820×312 canvas. Empty areas are filled with white. Use this when you must preserve every pixel of the original without any cropping.

How to Resize an Image for Facebook Cover — 3 Steps

Step 1: Upload Your Image

Drag and drop any JPG, PNG, WebP, or GIF into the upload area, or click "Select Image" to browse. The original dimensions appear immediately in the file card.

Step 2: Choose a Background Mode

Select Fill to crop edge-to-edge for a clean banner look — ideal for most photos. Choose Blur Background to keep the full image visible on a cinematic blurred backdrop — perfect for portrait or square photos. Use Fit to add white bars when every pixel of the original must stay visible. Then pick your output format (JPG, PNG, or WebP).

Step 3: Resize and Download

Click "Resize for Facebook Cover." A preview appears at the exact 820×312 px output. Click "Download Cover Image" to save the file — ready to upload directly to your Facebook Page.

Frequently Asked Questions

What is the correct Facebook cover photo size?

820 × 312 pixels is the recommended size for Facebook Page cover photos on desktop. Facebook scales and crops the image to 640 × 360 pixels on mobile. Using the correct 820×312 dimensions ensures your cover looks great on desktop while keeping the most important content within the central 640×312 safe zone for mobile viewers.

What is the Facebook cover photo safe zone?

Keep all text, logos, and critical visual elements within the central 640 × 312 px area of the canvas. The 90 px on each side of an 820×312 image are cropped on mobile devices. Content placed outside the safe zone may not be visible to mobile users.

What is the difference between 820×312 and 851×315?

851 × 315 px was the original Facebook cover size specification. Facebook updated the recommended dimensions to 820 × 312 px, which better matches the actual rendered area. Both sizes are accepted by Facebook — 820×312 is the current standard.

Is my image uploaded to a server?

No. All resizing happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device, is never stored on any server, and is never shared with anyone.

Which format should I choose — JPG, PNG, or WebP?

Use JPG for photos — it produces the smallest file size and Facebook handles it best. Use PNG if your image has a logo or text that needs a crisp, lossless result. Use WebP for the best balance of quality and file size if you also plan to use the image on a website.

Will resizing reduce image quality?

Downscaling from a high-resolution source to 820 px wide produces very little visible quality loss. Upscaling — making an image larger than its original size — will cause visible softness. Always start from the highest resolution source you have.

Does this work for Facebook Group and Event covers too?

Facebook Group covers display at 1640 × 856 px (cropped to 1640 × 664 px on desktop). Facebook Event covers display at 1920 × 1005 px. This tool is optimized for Facebook Page covers at 820 × 312 px. For groups and events, use the custom dimensions option in our Social Media Image Resizer.
