Resize Image for Facebook Cover

What This Tool Does

Facebook displays cover photos at different sizes depending on the device. On desktop, the cover photo shows at 820 by 312 pixels, while on mobile it appears at 640 by 360 pixels. This tool adjusts your image's width and height so it fits within these dimensions correctly.

Use it when you're updating a personal profile, a business page, or a group cover photo. The goal is a cover image that looks sharp and properly framed, not stretched or cut off in unexpected places.

Recommended Dimensions

Since Facebook compresses and crops cover photos differently across devices, many creators upload a slightly larger image to avoid blurriness. A common recommendation is 1200 by 630 pixels, which gives Facebook enough resolution to scale the image down cleanly for both desktop and mobile views.

If your original photo has different proportions, resizing it directly to 820 by 312 pixels can cause important content to sit outside the visible area on mobile. Uploading a larger image and letting Facebook adjust the crop often produces better results.

Aspect Ratio

The Facebook cover photo area uses a wide, horizontal aspect ratio, roughly 2.7:1 on desktop. Photos with a similar ratio resize cleanly without leaving empty space or cutting off the subject. If your image is closer to a square or portrait shape, expect visible cropping on the sides or top after resizing.

How to Resize an Image

1. Upload the photo you want to use as your cover image.
2. Enter the target width and height, or choose a Facebook cover preset if available.
3. Check the aspect ratio to confirm the subject stays within the visible frame.
4. Preview the resized image before saving.
5. Download the resized file and upload it to your Facebook profile or page.

Best Practices

• Keep important faces or text away from the edges, since mobile and desktop crop the image differently.
• Upload a slightly larger image than the display size to avoid pixelation after Facebook's compression.
• Maintain the original aspect ratio when possible to prevent unwanted stretching or squeezing.
• Preview how the cover looks on both desktop and mobile layouts before publishing.

Common Mistakes

• Resizing to the exact mobile dimensions, which causes desktop viewers to see a cropped or oddly framed image.
• Placing text or logos too close to the edges, where they get cut off on smaller screens.
• Using a low-resolution source image, which becomes blurry once stretched to cover photo size.
• Ignoring the aspect ratio and forcing a square photo into a wide frame, distorting the subject.

Conclusion

A properly sized cover photo helps your Facebook profile or page look polished across every device. Resize your image with the correct proportions in mind, and take a moment to preview it before uploading.
