Drop an image below and this tool resizes it to 1584×396 pixels, entirely inside your browser — no upload, no install, no sign-up. LinkedIn's profile background banner renders at a wide 4:1 ratio — 1584×396 fills it edge-to-edge on both desktop and mobile.
With aspect ratio lock on (the default), the tool computes the matching dimension from your image's own proportions so the result isn't stretched or distorted — it never crops your photo. Turn the lock off if you need to hit this exact box regardless of your image's original shape.
