What LinkedIn ads asks for, covered.
Herofab's ad creative tool delivers a square at 2,048 × 2,048 pixels and a 4:5 portrait at 1,640 × 2,050, both inside the minimum and maximum sizes LinkedIn sets for single image ads and above its recommended sizes. Herofab has no 1.91:1 ratio: the 16:9 banner is its closest horizontal format and has to be cropped. A 2K PNG can weigh more than the 5 MB limit for single image ads, so the JPG download is the safer file.
