How to Compress Images for LinkedIn: Optimal Sizes and File Formats
LinkedIn compresses all uploaded images, so uploading a 10MB photo wastes bandwidth and often results in worse quality than a properly sized file. The sweet spot is under 2MB with dimensions that match or slightly exceed LinkedIn's display size.
Recommended LinkedIn Image Sizes
| Image Type | Optimal Dimensions (px) | Max File Size | Best Format |
|---|---|---|---|
| Profile Picture | 400 × 400 | 2MB | JPG or PNG |
| Personal Banner | 1584 × 396 | 2MB | JPG or PNG |
| Single Post Image | 1200 × 1200 (square) or 1200 × 675 (landscape) | 2MB | JPG |
| Multi-Image Post | 1080 × 1080 (square) or 1920 × 1080 (portrait) | 2MB | JPG |
| Article Featured Image | 1200 × 644 | 2MB | JPG or PNG |
| Company Logo | 300 × 300 | 2MB | PNG (transparent) |
How to Compress Images for LinkedIn
Step 1: Resize to the right dimensions first. Never upload a 5000px wide photo. Scale down to 1200–1600px on the longest side.
Step 2: Export as JPG at 80% quality. This typically drops file size by 60–70% with minimal visible loss.
Step 3: Run it through a compressor. Use a free tool like TinyPNG, Squoosh, or ImageOptim to strip metadata and further reduce file size.
Step 4: Verify it's under 2MB. If it's not, lower quality or resize further.
LinkedIn's Compression Rules
LinkedIn automatically:
- Converts PNGs to JPG
- Reduces images over 2000px to ~2000px
- Strips EXIF data
- Applies its own lossy compression
This means a 10MB RAW file often looks identical to a properly compressed 1.5MB JPG after LinkedIn processes it—but the compressed version uploads instantly.
Common Mistakes to Avoid
- Uploading 4K photos — Way more data than needed, and LinkedIn compresses anyway.
- Using PNG for everything — PNGs are larger; use JPG for photos unless transparency is required.
- Ignoring aspect ratios — LinkedIn crops weirdly. Preview your crop before uploading.
- Forgetting mobile — 73% of LinkedIn traffic is mobile. Test how your images look on smaller screens.
