Compress Images for LinkedIn — Free, Fast & Private
LinkedIn images need to look professional while staying within platform limits. A blurry or pixelated profile photo, a stretched banner, or a poorly compressed post image creates a poor first impression. Using the correct dimensions and compression settings ensures your LinkedIn presence looks sharp and professional.
MiniPx compresses your LinkedIn images in your browser — no file uploads, no third-party processing. This is especially relevant for LinkedIn content because it often involves professional headshots, company logos, and business content you may not want processed on external servers.

LinkedIn banner optimization
LinkedIn banners at 1584x396px are wide and thin — a tricky 4:1 aspect ratio with its own dedicated LinkedIn banner size guide, including the different 1512x256 company page spec. The banner is cropped differently on mobile versus desktop, with the centre area always visible. Keep important content (text, logos) within the centre 60% of the banner. Compress to under 500KB for fast loading. LinkedIn compresses banners aggressively, so uploading a pre-optimized image gives you better results.
LinkedIn post images that get engagement
For a post that shares a link with a custom image, LinkedIn recommends 1200x627px (1.91:1); the ideal post image is 1200x627px (1.91:1 ratio) in JPEG format at 200-400KB. Infographics, charts, and carousel documents (.pdf) tend to perform well. For carousel-style posts, compress each page as a separate image and combine into a PDF using our Image to PDF tool.
