LinkedIn's optimal image size for feed posts is 1200x627 pixels. This dimension ensures your professional content displays sharply and takes maximum advantage of the LinkedIn feed layout on both desktop and mobile.
LinkedIn uses a similar aspect ratio to Facebook for shared images (approximately 1.91:1). Posting at the correct dimensions prevents LinkedIn from cropping or resizing your image, which can reduce quality and cut off important elements.
For LinkedIn articles (long-form posts), the cover image should be 1200x644 pixels. For company page banners, use 1128x191. Personal profile banners should be 1584x396. All of these follow different aspect ratios, so plan your content accordingly.
To resize for LinkedIn with ImgTools, upload your image and enter 1200 for width and 627 for height. For professional headshots being used in posts, consider cropping to frame the subject well within the landscape format before resizing.
LinkedIn supports square posts (1080x1080) and portrait posts (1080x1350) as well, following Instagram's lead. The portrait format takes up more feed space and can increase engagement, just like on Instagram.
Save LinkedIn images as JPEG at 80-85% quality for a good balance of file size and visual quality. Professional content should look crisp, so avoid aggressive compression. Keep files under 5 MB.
