Converting HEIC to JPEG for LinkedIn Posts
iPhones save photos as HEIC by default, and not every site accepts it. 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.
Converting HEIC to JPEG
When you pick photos through the browser file picker, iOS usually converts them to JPEG automatically. On other systems, open the HEIC in your photo app and export as JPEG.
Once you have a JPEG, compress it to around 400 KB for LinkedIn posts. JPEG is accepted almost everywhere.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.

- 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.
