Upload Errors and File Size Limits for LinkedIn Posts
An upload error is frustrating when the message is vague. 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.
Upload Errors and File Size Limits
Most errors come from three causes: the file is too big, the dimensions are outside the allowed range, or the format is not accepted.
For LinkedIn posts, convert to JPEG, resize to about 1200 pixels and compress below 400 KB. If the form lists its own limits, use those numbers instead.
