## What Face Swap is for

* Putting a character you built into a scene you generated separately
* Consistency fixes where one image in a set came out slightly off
* Your own likeness in your own compositions

## How to use Face Swap

1. Open Face Swap and upload the image you want to change.
2. Upload the face you want to use.
3. Run it, then check the edges around the hairline and jaw, which is where a swap shows first.

## Limitations

* Generating a recognizable real person without their consent is not permitted on Mage. See the content rules.
* It swaps the face only, so the head shape stays. Very different face shapes, strong angles, or heavy occlusion produce visible seams. Character Swap replaces the whole subject and handles those cases better.
