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.
| 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) |
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 automatically:
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.
Getting your images right improves load times, engagement, and how professional your profile looks—especially for your profile picture and banner, which are the first things recruiters and clients see.
