LinkedIn is the dominant platform for professional content, and image quality directly affects how far your posts travel in the feed. An incorrectly sized image gets cropped awkwardly or displayed at reduced quality. This guide covers every LinkedIn image type in 2026 — from single-image posts to carousels and article headers — with exact pixel dimensions and format recommendations.
LinkedIn Single Image Post Size
- Recommended size: 1200×628 px (1.91:1 landscape ratio) for link previews and shared content
- Square posts: 1080×1080 px — performs well in the feed and is favored by LinkedIn's algorithm for organic posts
- Portrait posts: 1080×1350 px (4:5 ratio) — takes up more vertical feed space and can increase engagement
- Maximum file size: 8 MB per image
- Supported formats: JPEG, PNG, GIF (static only in posts)
- Minimum dimensions: 552×276 px, though this produces noticeably low-quality results in the feed
LinkedIn Carousel (Document) Post Size
LinkedIn carousels are uploaded as PDF documents, not as individual images. Each "slide" is one page of the PDF.
- Recommended slide size: 1080×1080 px (square) or 1920×1080 px (16:9 landscape)
- Maximum PDF file size: 300 MB (maximum 300 pages)
- Best practice: design slides at 1080×1080 px for consistent display across desktop and mobile
LinkedIn Article Cover Image Size
- Recommended size: 1200×628 px (1.91:1 ratio)
- Displayed size: the cover is shown at approximately 700×400 px in the article header, but higher resolution uploads look sharper on retina displays
- File size limit: 8 MB
LinkedIn Link Preview Image Size
When you share a URL on LinkedIn, the platform pulls the OpenGraph image from the linked page and displays it as a link preview card.
- Ideal OpenGraph image size: 1200×628 px
- Minimum size for preview card: 1200×627 px
- Images smaller than 1200 px wide: LinkedIn may display them as a small thumbnail instead of a large card — significantly reducing click-through rates
Best Format for LinkedIn Images
- JPEG: best for all photographic content. Compress to quality 85–90 before uploading. Target 300–500 KB for most posts — LinkedIn re-encodes uploaded images, but starting with good quality prevents double compression artifacts
- PNG: use for graphics, text-heavy images, logos, and diagrams where sharp edges matter. PNG preserves text clarity that JPEG compression degrades
- WebP: LinkedIn supports WebP uploads. WebP files are 25–35% smaller than JPEG at the same quality — ideal for reducing upload time
How to Prepare LinkedIn Images
- Resize to target dimensions: use image resizerto crop and resize your image to 1080×1080 px for square posts or 1200×628 px for link preview images
- Compress before uploading: use image compressorto reduce file size to under 500 KB. This speeds up your upload and LinkedIn's re-encoding produces cleaner output from a higher-quality source
- Optional: convert to WebP: use image converterfor 25–35% smaller files without visible quality loss
LinkedIn Profile and Background Image Sizes
- Profile photo: 400×400 px recommended (minimum 200×200 px), shown as a circle — center your face and leave some margin around the edges
- Background/cover photo: 1584×396 px (4:1 ratio) — this area is cropped differently on mobile vs. desktop, so keep key content in the center 60% of the image
- Company logo: 300×300 px, PNG with white or transparent background
- Company cover image: 1128×191 px
Tips for Higher LinkedIn Engagement
- Square images (1080×1080 px) consistently outperform landscape images in organic reach because they take up more vertical space in the feed
- Add alt text to LinkedIn images via Settings & Privacy → Accessibility to make your posts accessible and indexable
- Text on images should use high contrast. LinkedIn's feed can display images in both light and dark modes — test your image against both backgrounds
- Use image resizer to create multiple versions of the same image at different aspect ratios for testing what performs best with your audience
