LinkedIn is a professional network where image quality reflects your personal brand. Incorrectly sized or heavily compressed images look unprofessional. Here is how to compress images for LinkedIn posts while keeping them sharp and professional.
LinkedIn Image Upload Limits
| Content Type | Max File Size | Recommended Size |
|---|---|---|
| Post image | 5 MB | 1200×628 px |
| Article image | 10 MB | 1200×644 px |
| Profile banner | 8 MB | 1584×396 px |
Compressing for LinkedIn Posts
Upload your image to imgresizr.com. Resize to 1200×628 pixels for the ideal LinkedIn post image — this fills the preview perfectly without cropping. Use the Compress tool to set JPG quality to 90%. This balances file size (roughly 200–500KB) with the visual quality expected on a professional network. Download as JPG and post directly to LinkedIn.
LinkedIn Image Format Guide
- Photos: JPG at 90% quality — rich colours, suitable file size
- Screenshots and graphics: PNG — preserves text sharpness
- Infographics: PNG — avoid JPG compression artefacts on detailed graphics
- Documents shared as image posts: PNG — cleaner than JPG for text
LinkedIn Post Image Best Practices
- Use 1200×628px (1.91:1 ratio) for images that appear in the feed preview without cropping
- Include your brand colour and logo on educational graphics
- Avoid images with too much text — LinkedIn reduces reach for text-heavy images (similar to Facebook)
- Consistently sized images across your posts create a professional, recognisable feed
