PDFConvertersOnline.comHow to resize a Facebook cover photo
- Add the image you want as your cover.
- 851×315 is already selected. Drag the preview so the key part sits near the middle.
- Resize, download the JPG and set it as your cover on Facebook.
The numbers Facebook gives
According to Facebook's help center, a Page cover photo:
- displays at 820 pixels wide by 312 pixels tall on computers,
- displays at 640 pixels wide by 360 pixels tall on smartphones,
- must be at least 400 pixels wide and 150 pixels tall,
- loads fastest as an sRGB JPG file that is 851 pixels wide, 315 pixels tall and less than 100 kilobytes.
This page uses that 851×315 size. For covers with logos or text, Facebook suggests a PNG file may look better.
One picture, two different crops
Look closely at those display sizes. On a computer the cover is a long, thin strip (about 2.6:1). On a phone it is much closer to a 16:9 rectangle, so it shows more height but less width. The same file is trimmed differently depending on where it is seen: the phone view cuts off the left and right sides.
The practical rule is to keep everything important, such as faces, logos and slogans, in the central part of the image, with only background at the far edges. Drag the preview here to put your subject in the middle before you download.
Keeping it sharp and light
The output is a JPG by default; move the quality slider down a little if you want to get under the 100 KB that Facebook mentions for fastest loading. You can check the file size on the result screen, and if it's still too big, run it through Compress Image to 100KB. If your cover contains lettering or a logo with fine edges, choose PNG as the output format instead, which avoids smudgy halos around text.
Using a photo that is the wrong shape
Most photos are 3:2 or 4:3, far taller than a cover. Crop to fill keeps a horizontal band of the photo, which works well for landscapes and group shots taken from a distance. For a portrait-style picture, Fit with background keeps the whole picture and fills the sides with a color you choose, a clean option for a product or book cover. Want to add a slogan afterwards? Use Add Text to Image.
Checking before you publish
After uploading, Facebook lets you drag the cover to reposition it before saving. Since your file already has the right proportions, there is little to move; just confirm that nothing important sits under the profile picture or the Page name. Then open the Page on your phone to see the narrower view. If a logo is cut off there, come back, drag the frame so the logo moves toward the center, and resize again.

What size is a Facebook cover photo?
Facebook suggests 851×315 pixels as a JPG under 100 KB for fastest loading. It displays at 820×312 on computers and 640×360 on phones.
Why does my cover look cut off on my phone?
The phone view is a different shape, so the sides are trimmed. Keep important content toward the center.
Can I use a PNG?
Yes. Facebook's help says PNG may give better results for covers with a logo or text. Choose PNG under Format.
My photo is too small. Can I enlarge it?
You can scale up to 851×315, and the minimum Facebook accepts is 400×150. Enlarged photos look softer, so use the biggest original you have.
