Free Facebook Cover Photo Resizer
This free tool resizes images to Facebook's cover, post and story sizes in your browser, and shows you what a phone will crop off a cover photo before you upload it.

Use the biggest version you have — every size is cut from it, and the largest banner asks for 2560px across.
Runs entirely in your browser. Your images are never uploaded to a server.
How it works
- Drop an image onto the box above, paste one with Ctrl+V, or click to choose a file.
- Tick the sizes you need. The feed post and story are ticked already; add the page cover if that is what you came for.
- Drag the picture to position it and zoom for more room. Each size keeps its own framing.
- Switch the cover preview between Desktop and Phone. A phone crops the sides off a cover photo, and the dashed box shows what survives both.
- Choose a file type, name them once, and download.
Common use cases
- Fitting a wide photo to a page cover without the important part being cropped off on phones.
- Sizing a shared image to 1200 x 630 so the link preview is not letterboxed.
- Making a story from a landscape photo, positioned so the subject stays clear of the interface.
- Producing a cover and a matching feed post from the same shot in one pass.
Frequently asked questions
- What size is a Facebook cover photo?
- 1640 x 856 is the size to upload. The catch is that it is not all visible everywhere — a phone crops the sides off, so a cover composed to look right on a laptop can lose its edges entirely on mobile. The preview here shows both.
- Why does my cover photo look wrong on my phone?
- Because Facebook shows a narrower slice of it on a phone than on a desktop. Anything near the left or right edge is at risk. Keep the important part within the dashed box on the phone preview and it will survive both.
- What size should a Facebook post image be?
- 1200 x 630 for a standard shared image or link preview, which is also the size Facebook uses when it generates a card for a URL. A 1080 x 1080 square fills more of a phone feed and is worth using when the image can take it.
- Can I set each size differently?
- Yes. A cover is extremely wide and a story is extremely tall, so one framing almost never suits both. Each size keeps its own position and zoom, and one framing can be copied across all of them when they do agree.
- Are my images uploaded to a server?
- No. Everything happens in your own browser using the Canvas API. The files never leave your device, and nothing is stored.
