Facebook Cover Photo Resizer — 851×315
Resize images to Facebook cover size 851×315. Nail the desktop banner crop on the first try.
About the Facebook Cover
Get pixel-perfect Facebook cover photo output every time: images are drawn onto a 851×315 canvas, so what you upload is what the platform receives. The fit selector decides between center-cropping (cover) and padded fit (contain), with JPEG, PNG or WebP export.
How it works
The tool produces exactly 851×315 pixels — Facebook's desktop cover ratio (roughly 2.7:1). Cover mode center-crops your image into that wide strip; contain pads it over a background color you choose. Either way, what you preview is what the banner shows on desktop.
How to use it
Drop up to 10 images, pick a fit mode, set a pad color if containing, and process. Check that key content sits within the wide center band before downloading.
Supported formats & limitations
Accepts .jpg, .png and .webp up to 30MB each, 10 per run. Mobile crops the sides of cover photos — keep logos and faces near the horizontal center so both viewports behave.
Common use cases
Business page covers, event banners, community group headers, and personal profile art. Pairs naturally with the Facebook Profile tool when branding a whole page in one sitting.
Frequently asked questions
How large is the facebook cover canvas?
851×315 pixels. Your picture is drawn onto that exact canvas, so the upload meets the platform's spec without any manual trimming.
Is 851×315 the same in inches?
Platform sizes are pixel-based, not physical. If you need a print comparison: at 300 DPI, 851×315 px is about 7.2×2.7 cm — or 2.84×1.05 inches.
What does the fit option change?
It controls how your picture meets the 851×315 frame: cover crops to fill every pixel, contain preserves the entire image and fills gaps with padding, stretch forces exact dimensions by distorting proportions.
How many images can I resize in one go?
10 per batch — each is output at exactly 851×315 px with identical fit and quality settings, ready to download separately or zipped together.
