How to Compress Images for LinkedIn Posts on Windows
On Windows, a browser-based compressor avoids installing extra software. Professional feeds load on slow office Wi-Fi and phones alike, so a compact image keeps your post readable on every connection.
Recommended settings for LinkedIn posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 78 |
| File size | 400 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
How to Compress Images
Open Edge, Chrome or Firefox, drag your photos from File Explorer into the drop zone, and set quality around 78.
For several files, use Download all to get a single ZIP. Extract it and your images are ready for LinkedIn posts with the original files untouched.
