Quick Guide: Compress JPEG for Facebook Posts in 30 Seconds
Short on time? Here is the fastest route. Facebook re-encodes uploads, and starting from a clean, right-sized JPEG gives it less room to introduce blocky artefacts.
Recommended settings for Facebook posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 2048 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.
