Image File Size Checklist for Facebook Posts
Run through this list before you upload. 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.
Image File Size Checklist
Is it the right format? Photos should be JPEG or WebP. Is it the right width? Around 2048 pixels suits Facebook 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.
