Resize an image for LinkedIn

Because it is a banner rather than a picture: it sits behind and around your profile photo, and its centre is partly covered on some layouts. A 4:1 strip is an unusual shape for a photograph, so images with a single subject in the middle rarely survive the crop. Wide scenes, textures and graphics work far better than portraits.

A square if the image is the point, because it occupies the most vertical space in a phone feed and stops the reader scrolling. The wider 1200 x 627 shape is the right choice when the image accompanies a link, because that is the shape the link card itself uses and a mismatch looks like two different pictures.

It publishes limits that differ by surface, and this tool does not apply one. That is deliberate: imposing a byte ceiling we have not verified would degrade your image to satisfy a number we cannot vouch for. If your upload is refused for size, use the compressor afterwards and you will be able to see exactly what you are trading.

Usually, but check it. Resizing a screenshot or a slide down to a post size makes small text noticeably softer, and JPEG compression is at its worst around sharp edges like letterforms. If the image is mostly text, keep it as large as the shape allows and consider whether it should be a document post instead.

They are the figures independent references consistently report, and the page labels them as such rather than as requirements. LinkedIn does publish guidance on image sizes; it was not re-read while these presets were written, so calling them official would claim a check that did not happen.
