Batch Compressing Photos for LinkedIn Posts
When you have dozens of images, consistency matters as much as size. 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.
Batch Compressing Photos
Drop all the files at once. The same settings are applied to each, so a set of photos for LinkedIn posts ends up with matching dimensions and similar file sizes.
Use Download all to collect everything in one ZIP. A target of 400 KB per image keeps the whole batch predictable.
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.
