Resize Image for Facebook Cover Photo (820×312)
Create the perfect Facebook cover photo at 820×312 pixels. Resize profile pictures, event banners, and group headers. Free online tool, no signup.
Your Facebook cover photo is the first thing visitors see on your profile or business page — it's your digital billboard. But Facebook's recommended dimensions (820×312 pixels on desktop, 640×360 on mobile) create a unique challenge: the image must look good at two very different crops. Upload the wrong size and you'll get awkward cropping, blurry stretching, or important elements cut off on mobile.
Our resizer takes the guesswork out of the process. Upload any image, set the dimensions to 820×312, and preview exactly how it will appear. For the sharpest results, work with an image that's already close to the 2.63:1 aspect ratio, or use our tool to crop and scale simultaneously. The preview shows you the safe zone where text and logos should be placed to avoid getting clipped on any device.
Beyond cover photos, this tool handles every Facebook image type: shared images (1200×630), event covers (1920×1005), and group headers (1640×856). Switch between presets to prepare your entire social media kit in one session. Everything processes locally — no third-party server ever touches your images.

Facebook recommends 820×312 pixels for desktop and 640×360 for mobile. For best results, create at 820×462 pixels — this covers both desktop and mobile crops. Keep important content centered to avoid mobile cropping.
Blurry cover photos are usually caused by uploading an image that's too small (under 820px wide) or using a highly compressed JPG. Upload at the exact recommended dimensions and keep quality above 80% for sharp results.
You can, but Facebook will convert it to JPG anyway and apply its own compression. For photographs, upload a high-quality JPG. For graphics with text or logos, PNG may preserve edges better despite the conversion.
