The honest answer is that it depends on what the tool did to your face. Redrawing you is a problem. Relighting and cropping the photo you actually took is not.

The limits are 400x400 to 7680x4320 pixels, under 8MB, PNG or JPG. The more useful part is what LinkedIn does to your photo after you upload it.

Usually yes, and the reason has nothing to do with looking friendly. A held smile is what goes wrong, not smiling itself. Here is how to get one that looks like you.

A headshot has three jobs: be recognisably you, match the room you are walking into, and survive being shrunk to 48 pixels. Everything else is decoration.

Almost always one of four things, and only one of them is about the original photo being soft. The other three you can fix in a couple of minutes.

Most places show you a circle or a square. A few want a portrait rectangle. Shoot once with room around you and you can produce all of them from the same frame.

You upload one square and get a circle here, a wide banner there, and your chin missing on the third. The fix is to build the photo for the worst crop rather than the best one.
