How it works
- 1Drop your cover image in — a wide photograph or a designed banner.
- 2It is scaled and center-cropped to 851 × 315, the size Facebook displays on desktop.
- 3Remember that mobile shows a taller, narrower slice of the same file: keep text away from the left and right edges.
Frequently asked questions
- Why do desktop and mobile show different parts of my cover?
- Because the same file is fitted to two different shapes. Desktop uses the wide 851 × 315 framing; the mobile app shows a taller, narrower crop of the same image, trimming the sides. Text placed near either edge reads perfectly on a computer and vanishes on a phone.
- Where does the profile picture overlap?
- Over the lower-left of the cover on desktop layouts, and centred over the lower portion on some mobile views. Neither position is fixed forever, which is the argument for keeping the bottom strip of the cover free of anything you need people to read.
- My cover looks blurry after uploading. What causes that?
- Almost always a source image smaller than the display size, scaled up by Facebook. The other cause is heavy re-compression of a large upload. Providing a file already at 851 × 315, sharp and reasonably compressed, removes both — Facebook has nothing left to resize.
- Can I use the same image for a page and a personal profile?
- Yes — both use the same wide cover shape, and this size works for either. The layouts around them differ slightly in where the profile picture and buttons sit, so a design that keeps its content centred and away from the bottom edge transfers between them safely.
About this tool
A Facebook cover is one image asked to work in two shapes. The desktop layout shows the wide 851 × 315 framing this tool produces; the mobile app crops the same file taller and narrower, trimming the sides. Any text or logo near the left or right edge is therefore visible on a computer and simply gone on a phone, which is the single most common cover-photo mistake.
The bottom of the frame is the other unreliable region. Your profile picture overlaps the lower-left on desktop and sits differently again on mobile, and Facebook has moved these elements more than once over the years. Keeping the meaningful content in the upper-centre of the cover is what makes a design survive both the current layout and the next one.
Uploading at the display size also prevents the two usual causes of a blurry cover: a small image being scaled up, and a very large one being aggressively re-compressed. This tool scales your photo to fill the frame, crops evenly from the centre so nothing is distorted, and compresses the result — locally in your browser, with nothing uploaded here and your original left untouched.
