# Face Swap

> Seamlessly replace faces in images and videos — 5 credits for images, 15 credits for videos

# Face Swap

Replace any face in an image or video with AI. Upload a base file (image or video) and a face reference photo — the AI seamlessly composites the face with natural lighting and expression matching.

**Credit Cost:** 5 credits (image) | 15 credits (video)\
**Access:** [app.wrldwide.ai/face-swap](https://app.wrldwide.ai/face-swap)

## Key Features

<AccordionGroup>
  <Accordion title="Consistent Video Swapping">
    Video mode maintains face consistency across all frames — the swapped face doesn't flicker or drift as the subject moves, making it suitable for actual video content.
  </Accordion>

  <Accordion title="Lighting Adaptation">
    The AI analyzes the lighting in the base file and applies matching lighting to the swapped face. Dark-lit base videos get appropriately shadowed face swaps, not unnaturally bright faces.
  </Accordion>

  <Accordion title="Angle Handling">
    Works across a range of face angles — frontal, 3/4, and profile to a degree. Best results with source material that roughly matches the reference face angle.
  </Accordion>

## Tips for Best Results

### Base File Tips

* **Lighting** — Consistent, well-lit face in base material gives the best swap
* **Resolution** — Higher resolution base = more realistic output
* **Angle** — Match face angles between base and reference when possible

### Reference Face Tips

* **Clarity** — Use a sharp, in-focus photo
* **Lighting** — Avoid harsh shadows or extreme lighting
* **Expression** — Neutral expression works for widest compatibility
* **Single face** — Only one face should be prominently visible
