A blurry, awkwardly cropped Facebook cover photo is one of the fastest ways to make a profile or business page look unprofessional. The good news is that fixing it takes about two minutes once you know the exact dimensions Facebook expects. This guide walks you through the correct cover photo sizes, how to resize an image for a Facebook cover photo step by step, and how to keep your file sharp after Facebook's compression.

What Are the Correct Facebook Cover Photo Dimensions?

Facebook's recommended cover photo size is 851 pixels wide by 315 pixels tall. That is the number to aim for when you resize your image. However, there is an important catch: Facebook displays your cover differently depending on the device.

• Desktop: displays at 820 x 312 pixels
• Mobile (smartphones): displays at 640 x 360 pixels

Because of this, mobile crops the left and right edges of your image, while desktop crops the top and bottom slightly. Anything important — text, a face, a logo — should sit in the central area of the image, roughly the middle 640 x 312 pixels, so it survives both crops.

Facebook also has minimum requirements. If you upload an image smaller than 400 x 150 pixels, Facebook will either reject it or stretch it, which causes visible blurring. For the sharpest result, many designers upload at 1640 x 664 pixels or 1920 x 712 pixels — exactly double (or slightly more than double) the display size — so the image stays crisp on high-resolution screens.

File format matters too. Use JPG for photographs and PNG for images containing text, logos, or flat graphics. Facebook compresses everything you upload, and PNG handles sharp edges and lettering far better than JPG.

How to Resize an Image for a Facebook Cover Photo (Step by Step)

You do not need Photoshop or any paid software. A free browser-based tool handles the whole job.

Step 1: Choose the right source image. Pick a landscape-orientation photo that is wider than it is tall. A vertical phone photo will force you to crop away most of the image, so start with something shot horizontally if possible.

Step 2: Crop to the correct aspect ratio. The cover ratio is roughly 2.7:1 (851 divided by 315). Crop your photo to this ratio first so nothing important gets cut off unexpectedly. Keep your subject centered, with breathing room on the left and right edges for the mobile crop.

Step 3: Resize to the exact dimensions. Use the free online image resizer to set your image to 851 x 315 pixels, or 1640 x 664 pixels if you want a sharper result on retina displays. Enter the width and height, make sure the aspect ratio matches, and download the result.

Step 4: Check the file size. Facebook cover photos upload fine at almost any size, but smaller files upload faster and give Facebook's compressor less work to do. If your resized image is heavier than you would like, run it through the image compressor to 100KB — 100KB is more than enough for a cover photo at these dimensions, and the quality difference is invisible at display size.

Step 5: Upload and preview on both devices. Go to your Facebook profile or page, hover over the cover area, and click "Add Cover Photo" or "Update Cover Photo." After uploading, check the page on your phone as well as your computer to confirm nothing important is cropped out. If the edges get clipped on mobile, reposition the photo or resize it with more margin around your subject.

Common Facebook Cover Photo Mistakes to Avoid

Placing text near the edges. This is the number one mistake. Desktop shows a wider, shorter slice of your image; mobile shows a narrower, taller one. Text placed near the left or right edge will disappear on phones. Keep all wording within the safe central zone.

Forgetting the profile picture overlap. On desktop, your profile picture sits on top of the lower-left portion of the cover photo. Do not put a logo, face, or key text in that bottom-left corner — it will be hidden behind your profile photo.

Uploading a low-resolution image. A 500 x 185 pixel image technically uploads, but it will look soft and pixelated. Always resize up to at least 851 x 315, and preferably higher.

Using JPG for text-heavy graphics. JPG compression creates fuzzy artifacts around lettering. If your cover includes a slogan or business name, save it as a PNG instead. If your source file is in WebP format — common when you download images from websites — convert it first with the WebP to JPG converter or the WebP to PNG tool, since older editing workflows handle JPG and PNG more reliably.

Ignoring file weight on event or group covers. Facebook event covers use a different size — 1200 x 628 pixels — and group covers use 1640 x 856 pixels. Check which type of cover you are creating before you resize, so you do not end up with an awkward auto-crop.

How to Compress Your Cover Photo Without Losing Quality

Facebook recompresses every image you upload, sometimes aggressively. The best defense is to upload an image that is already optimized: correct dimensions, sensible file size, and the right format.

For photographic covers, resizing first and then compressing to around 50-100KB produces an image Facebook barely needs to touch. The JPEG compressor to 50KB works well for standard photos, while graphic-heavy PNG covers can go through the PNG compressor to 100KB to strip out unnecessary file weight without touching visible quality.

One practical tip: avoid uploading a 10MB photo straight from your camera. Facebook will crush it with its own compression, often producing banding in skies and gradients. A properly resized, lightly compressed image almost always looks better after upload than a huge unoptimized original.

FAQ

What is the exact Facebook cover photo size in 2025?

Facebook recommends 851 x 315 pixels for profile and page covers. It displays at 820 x 312 pixels on desktop and 640 x 360 pixels on mobile, so keep important content centered. For sharper results on high-resolution screens, upload at double size: 1640 x 664 pixels.

Why does my Facebook cover photo look blurry?

Blurriness usually comes from uploading an image smaller than 851 x 315 pixels, which forces Facebook to stretch it. It can also happen when a very large file gets aggressively recompressed by Facebook. Resizing to the correct dimensions and compressing the file yourself before uploading fixes both problems.

Can I resize a Facebook cover photo without Photoshop?

Yes. Free browser tools handle everything you need. Crop your image to the 851:315 ratio, resize it with an online image resizer, and compress it if the file is large. The entire process takes a couple of minutes and requires no downloads or accounts.

Should I use JPG or PNG for a Facebook cover photo?

Use JPG for regular photographs — it produces smaller files with no visible quality loss in photos. Use PNG if your cover contains text, logos, or flat graphics, because PNG keeps sharp edges clean. Facebook accepts both formats for cover photos.

What is the safe zone for text on a Facebook cover?

The safe zone is roughly the central 640 x 312 pixels of your image. Mobile crops the sides of your cover, and desktop crops the top and bottom slightly, so anything outside the center risks being cut off on one device or the other. Also avoid the bottom-left corner, where your profile picture overlaps the cover.

Why is my Facebook cover cropped differently on my phone?

Facebook uses one uploaded image but displays it at different aspect ratios per device: wider and shorter on desktop, narrower and taller on mobile. That means the sides get trimmed on phones. Designing with centered content and generous margins ensures the cover looks correct everywhere.
