Expression close-up
Compare facial expression, not decorative effects
The main proof stays close to the face so you can inspect the mouth, eyes, eyebrows, and how naturally the expression changes.
Eyes and eyebrows
Surprise, seriousness, and confidence may adjust the eye area and eyebrow position to support the selected emotion.
Skin and detail
Skin texture, age, and small facial details should remain natural without a plastic beauty-filter look.
Mood spectrum
Several expressions, one tool
The Editor provides ready-made facial-expression presets, so you do not need to write a prompt. These are real directions from the current Emotion tool.
Smile
Serious
Surprised
Confident
Sad
What changes
Expression changes locally — identity stays recognizable
The Emotion tool targets facial expression. It is not intended to rebuild the portrait with a different hairstyle, outfit, or scene.
Facial expression
AI applies the selected emotion, such as a smile, serious look, surprise, confidence, and other presets.
Identity
Face shape, nose, eyes, jawline, and other individual features are instructed to remain unchanged.
Scene
Hairstyle, clothing, background, lighting, pose, and camera angle are not the target of this edit.
How it works

Upload a portrait

FAQ
Frequently asked questions
Can I change only the smile?
The current Emotion tool includes dedicated smile presets plus other ready-made facial expressions. Choose the expression you want before generation.
Are facial features preserved?
The tool prompt explicitly asks the model to preserve identity, age, and fine facial detail while changing the expression. As with any generative edit, review the result visually.
Can I try it for free?
An eligible guest can receive one successful demo generation globally across SmartGenius. After that, continuation happens through registration and the Editor.
Do I need a first Premium purchase to use Emotion presets?
No. Standard Emotion presets in the current Editor are not locked behind the first-purchase catalog rule; further generations use tokens according to the Editor rules.
Which image formats are supported?
Upload supports JPEG, PNG, and WebP. The current Editor configuration determines the maximum file size.
