A LinkedIn profile banner is 1584×396 pixels — a 4:1 letterbox that is wider and shallower than almost any other social header. The practical difficulty is not the resize, it is the layout: your profile photo sits over the lower-left of the banner on desktop, and mobile crops the visible area down to roughly 1350×220. Designs that look balanced in an editor routinely end up with their headline hidden behind an avatar.
Why 1584 × 396?
1584×396 is LinkedIn's stated size and it maps cleanly to a 2× render of 792×198, which is why it stays sharp on retina laptops — the audience most likely to be viewing your profile. LinkedIn accepts files up to 8 MB, which is generous enough that compression is rarely the constraint here. The constraint is composition.
What to Watch Out For
- Your profile photo overlaps the lower-left on desktop. Keep that corner empty.
- Mobile shows roughly the central 1350×220. Anything outside that is cropped away.
- A personal profile banner (1584×396) is not the same as a company page cover (4200×700). They are different pages and different sizes.
- Fine text under about 24px at this size becomes unreadable once LinkedIn scales the banner down on smaller screens.
Resizing Without Uploading
The resizing happens entirely in your browser. Your image is never sent to a server, which matters more than it sounds — most online resizers upload your file to a machine you know nothing about. Here there is nowhere for it to go, so the question does not arise. It also means the tool keeps working with no connection once the page has loaded.
