Compressing Portrait Photos for Facebook Posts
Faces are where viewers notice compression first. 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.
Compressing Portrait Photos
Smooth skin and soft backgrounds can show banding at low quality. Quality around 78 to 85 keeps tones natural.
Crop to head and shoulders when the image is shown small, as it often is for Facebook posts. A tight crop lets you use fewer pixels without losing detail where it matters.
