About this tool
Square 1200 by 1200 images take up more of the LinkedIn feed on phones than landscape ones, which makes them a popular choice for announcements, data points and quote cards. They also crop cleanly when LinkedIn shows previews at different sizes. Here it becomes that square, which takes more vertical space in the LinkedIn feed than a landscape image - worth more on mobile than the extra width.
How to use this tool

- Centre the messageKeep the headline or number in the middle of the square.
- Post itDownload and attach it to your LinkedIn post.
Square posts and document carousels
For single-image posts, a square with one clear message performs well. For multi-slide content, many creators upload a PDF document, which LinkedIn shows as a swipeable carousel; designing those slides square or at 4:5 keeps them consistent with your image posts.
