Resize for LinkedIn

The cover image behind your profile photo, often called the banner, is 1584 × 396: four times as wide as it is tall. A phone photo is usually 4:3 or 3:4, so turning it into a banner means keeping a thin strip of it.

With Fill, that strip is the middle of the photo. If it misses what matters, a horizon or a skyline, open Crop Image and slide the frame up or down; the banner stays 1584 × 396. For a logo or a slogan, Fit puts the whole image in the middle on a colour you choose.

Your profile photo sits over the left-hand part of the banner, so keep anything important away from that corner.

LinkedIn takes profile photos from 400 × 400 up to 7680 × 4320 pixels, as PNG or JPG files of up to 8 MB, and no GIFs. The Photo preset makes a square of exactly 400 × 400, the smallest it accepts; type a bigger square into the size fields if you want more detail.

The photo shows as a circle, so keep your face in the middle with a little room around it. Fill crops the photo to a square around its centre; Crop Image moves the square if your face is off to one side.

Company Pages have their own sizes, and a lower limit: every Page image must be a PNG or JPEG of at most 3 MB. The cover is 1512 × 256 and the logo 400 × 400, at least 268 × 268.

When a Page shares a link, LinkedIn asks for a 1.91:1 image of 1200 × 627. Other shapes appear in full with subtle white padding, so Fit with white borders gives you the same look, while Fill fills the whole width.

A JPG is re-saved once, at quality 90 out of 100, from your original; a PNG stays lossless.
