FULL-BODY TRANSFORMATION
Change the physique, not the person.
The visual focus is the overall silhouette and natural proportions rather than a local warp filter.
Silhouette
Changes physique and overall volume distribution.
Pose
Keeps the original body position and camera angle.
Scene
Clothing, background, and lighting should stay consistent with the source.
BODY MODES
AI Body Transformation Examples
Three different scenarios: a more athletic build, a slimmer silhouette, and a change in overall proportions.

AI BODY EDITOR
AI body editor — muscles, weight loss, and body shape change online
An AI body editor can visualize a different physique in a photo: a more athletic build, a slimmer silhouette, or a change in overall body volume. The model edits the image as a whole while aiming to preserve anatomy, clothing, pose, and surroundings.
01
Athletic build
More visible muscle tone, stronger shoulders and arms, and an overall athletic silhouette.
02
Slimmer
Gentle reduction of overall volume and slimmer proportions without manually warping the photo.
03
Shape and volume
A curvier, bulkier, or fuller physique depending on the selected option.
HOW IT WORKS
How to change body shape in 3 steps

A clear full-body or waist-up image works best.

Compare the result
Use Before / After, download the image, or continue editing in the full Editor.
PRESERVE THE SCENE
Why the result looks more natural than a simple warp
The Body tool sends the model a physique description plus constraints for keeping the rest of the image consistent, rather than stretching one selected area.
Face and identity
The edit is designed to keep the face, age, expression, and hairstyle consistent while changing body shape or proportions.
Clothes and pose
Clothing style, pose, and camera angle are preserved.
Anatomy
The model is instructed to keep realistic proportions and avoid warped limbs or extra anatomy.

FAQ
Frequently Asked Questions
Can I try Body for free?
Guests use the shared SmartGenius free AI try. After it has been used, you can create an account and continue in the full Editor.
Can I edit only arms, abs, or legs?
The current Body tool uses complete physique options and does not expose a separate body-area selector. For a localized change, use AI Correction or prompt-based editing instead.
Which body options are available?
Standard body options in the current Editor do not require a first-purchase catalog unlock. Separate male and female option groups are available.
Does it preserve the face and pose?
The Body prompt specifically asks to preserve the face, age, expression, hairstyle, clothing, pose, camera angle, background, and lighting. As with any generative edit, review the result before use.
