Image File Size Checklist for LinkedIn Posts
Run through this list before you upload. 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.
Image File Size Checklist
Is it the right format? Photos should be JPEG or WebP. Is it the right width? Around 1200 pixels suits LinkedIn posts. Is it under the limit? Aim for 400 KB or whatever the destination specifies.
Is it oriented correctly, cropped cleanly and free of private metadata? Our compressor handles orientation and strips metadata automatically when it re-encodes the image.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1200 and the target size to 400 KB.
- Press Compress, check the result and download it.
Quick tips
- Write a size limit slightly below the stated maximum to leave a margin.
- Process private images locally rather than uploading them to unknown servers.
- Crop out distractions so pixels go to the subject.
- Use WebP where it is supported and you control the page.

Wrapping up
For LinkedIn posts, the reliable recipe is simple: resize to around 1200 pixels, compress at quality 78 or to a 400 KB target, and check the result before you upload. Keep the original so you can always start again.
