Make a LinkedIn profile picture

400 x 400 is the size independent references consistently report for LinkedIn, and this page defaults to it with a larger option beside it. Platforms change display sizes without announcing it and re-encode what they receive, so treat it as the size that works rather than a specification LinkedIn is bound to.

Head and shoulders is what works, because of where the picture is shown. In a feed it renders small enough that anything further away than shoulders stops being legible, and the circular mask removes the corners - so a photograph framed for print loses exactly the parts that made it work.

The crop is square and LinkedIn draws a circle inside it, so the corners go. On LinkedIn that usually means the top of your head and the points of your shoulders - which is survivable. What is not survivable is a face placed off to one side, because the mask takes the side before it takes the middle. Crop the picture yourself first if the automatic centre is wrong; this page does not detect faces.

No. The crop and resize run in this page on your own device. The metadata is stripped from the download too, which matters here because a professional photograph is often taken somewhere identifiable and the file records where.
