Image Body Swap

Image Body Swap

Playground

Image Body Swap replaces the body in a target image with your face. Upload a face image and a body image to get a seamless swap. Ready-to-use REST inference API, no coldstarts, affordable pricing.

Features

Image Body Swap places your face onto any body image in seconds. Upload a face photo and a body photo — AI composites them together with natural blending, consistent lighting, and seamless results.

Why You’ll Love It

• Instant face-to-body compositing Advanced AI places your face onto any body photo with natural blending and consistent skin tone matching.

• Two-image simplicity No masks, no manual editing, no technical knowledge needed — just a face and a body.

• Endlessly versatile Swap onto fitness photos, fashion looks, fun costumes, or any creative scenario you can imagine.

How to Use

1. Upload your face image — a clear, front-facing portrait with good lighting works best.
2. Upload your body image — the photo whose body you want to swap the face onto.
3. Hit Run — your swapped portrait is ready in seconds.
4. Download and share.

Pricing

Just $0.05 per image.

Best Use Cases

• Fashion & styling — Try on outfits or looks without physically wearing them.
• Fun and social content — Swap onto wild, funny, or dramatic body photos for shareable posts.
• Creative projects — Composite faces into illustrations, costumes, or character designs.
• Personalized gifts — Put a friend’s face on a superhero, athlete, or iconic figure for a one-of-a-kind gift.

Pro Tips

• Use a clear, well-lit face photo with a front-facing angle for the most natural compositing result.
• Body images with a clearly visible, unobstructed upper body blend more cleanly.
• Similar face angles between the face image and body image produce the most realistic output.

Notes

• Both image and body_image are required fields.
• Ensure image URLs are publicly accessible if using links rather than direct uploads.
• Please ensure your content complies with WaveSpeed AI’s usage policies.
