Tips & Best Practices
Use 1200x1200 (square) for single-image posts — it works well across desktop and mobile feeds.
Portrait (1080x1350) takes up more screen space on mobile, which can increase engagement.
For link posts, set your Open Graph image to 1200x627 so the thumbnail looks sharp.
LinkedIn supports MP4 and MOV for video. Keep videos under 200 MB and 10 minutes long.
Native video outperforms YouTube links — upload directly to LinkedIn for higher reach.
Use PNG for images with text or graphics, JPG for photographs. Keep files under 10 MB.

Image Format Best Practices
LinkedIn supports JPG, PNG, and GIF (static only) for image posts. The platform re-compresses images on upload, so starting with a high-quality source is essential. For photographs, export as JPG at 85-95% quality — this keeps file sizes reasonable while preserving visual detail. For images containing text, logos, or graphic elements with sharp edges, use PNG to prevent compression artifacts around the lettering. LinkedIn displays images differently across devices. On desktop, the feed is narrower and images appear smaller. On mobile, images span the full screen width. Design your images to be readable on both by using large text (minimum 24px) and high-contrast colors. Avoid tiny details that might get lost on smaller screens.
Video Specifications
LinkedIn supports native video uploads up to 10 minutes long for regular posts (up to 15 minutes via the LinkedIn mobile app). The maximum file size is 5 GB, though files under 200 MB upload more reliably. Recommended encoding: H.264 video codec, AAC audio codec, MP4 container. For landscape video, use 1920x1080 at 30fps with a bitrate of 5,000-8,000 kbps. For vertical video, use 1080x1920 at the same settings. LinkedIn auto-plays videos on mute in the feed, so always add captions or text overlays. Posts with captions see significantly higher watch time because most LinkedIn browsing happens during work hours when audio isn't practical.
Algorithm and Engagement Tips
LinkedIn's algorithm favors content that generates meaningful engagement — comments, shares, and extended dwell time. Image posts with the right dimensions contribute to this by displaying clearly and taking up appropriate feed space. Square images (1:1) are the safest choice because they render consistently across all devices. Portrait images (4:5) can boost mobile engagement by occupying more screen real estate, but they appear smaller on desktop. Native documents (PDFs) and carousels consistently outperform single images in terms of engagement metrics. If your content involves multiple points or a narrative, consider using LinkedIn's document post format instead of a single image — it encourages swiping, which increases time spent on your content.
