Bloggers and LinkedIn writers who make pins already have a polished image for every post. Reusing it on LinkedIn is the obvious move, but a 2:3 pin gets cropped in the feed and in link previews, so the title is cut off. This tool keeps the whole pin and builds a LinkedIn sized image around it.
Choose the square 1080 × 1080, the taller 1200 × 1500 portrait or the 1200 × 627 link image, then set a brand color or a blurred copy of the pin as the background. Add a short title beside the pin to tell LinkedIn readers why they should click. The image is made in your browser and never uploaded.
Which LinkedIn size to choose
The 1200 × 1500 portrait (4:5) takes up the most room in the mobile feed, which suits a pin with a lot of text. The 1080 × 1080 square is the safe choice that looks the same everywhere, including Facebook and Instagram. The 1200 × 627 size matches the link preview card, so use it as a custom image when you share an article link.
In the square and link sizes, the title sits beside the pin. In the portrait size it sits above the pin, because a column next to a tall pin would be too narrow to read.
Writing the side title
The pin title was written for Pinterest search. On LinkedIn, people scroll a feed of colleagues, so the side title can speak to them directly: "New guide for freelance designers" or "What I learned pricing 40 projects". Keep it to a few words so it reads at feed size.
Going the other way? The LinkedIn post to pin tool turns a text post into a pin, and the pin to Instagram story tool makes a 9:16 story from a pin.
