Real directions
From a soft smile to laughter — without invented modes
The tool uses real Emotion presets from the current Editor: Soft smile, Big smile, Happy, and Laughing. It does not add invented extra modes.
Soft smile
A restrained expression when only a small adjustment is needed.
Big smile
A more visible friendly smile with natural-looking teeth.
Happy
The smile is supported by a more joyful eye expression.
Laughing
The most expressive option for a lively emotional portrait.
What changes
A believable smile is built from several facial cues
Changing only the mouth contour can look artificial. After generation, review the lips, teeth, cheeks, and the area around the eyes together.
Lips and teeth
The lip contour and visible teeth should match the camera angle instead of looking pasted in.
Cheeks and eyes
A smile subtly affects the cheeks and eyes, which helps the expression read as one whole.
Keep the scene recognizable
Hair, clothing, background, and pose are not the target of Smile editing and should stay stable.

How to add a smile to a photo
Upload a portrait
Choose a clear photo where the face is visible and not heavily occluded.
Choose a smile
Start with Soft smile or pick a stronger joyful expression when the photo calls for it.
Compare the result
Drag Before/After, review teeth and eyes, then download the result or continue in the Editor.
Where it helps
The smile should fit the context of the photo
The same smile intensity does not suit every portrait. A business photo usually benefits from restraint, while personal content can support a more lively expression.
Avatars and social media
Make an expression friendlier without rebuilding the portrait.
Business portraits
Add a subtle smile while keeping a calm professional look.
Family photos
Improve an awkward expression in an otherwise good frame.
Ads and content
Prepare a warmer expression for a thumbnail, card, or creative.
