How to Add a Smile to a Photo with AI

Start with a clear portrait and the expression you want. A short request is enough.

Upload Your Portrait

Choose a well-lit photo with a clearly visible face. Tell our AI smile generator whether you want a small, closed-mouth smile or a relaxed smile with teeth.

Create a Smiling Version

The AI agent uses your photo and request to create an edited version. Ask it to focus on the expression and retain your hairstyle, clothing, lighting, and background.

Fine-Tune the Expression

Click Chat Edit to ask for fewer visible teeth, a softer grin, or more relaxed cheeks. Make one focused change at a time, then compare with the original.

Check and Download

Zoom in on the lips, teeth, eyes, and face shape. Once the result looks right, download your smiling photo as PNG or JPG without a watermark.

A Smile That Fits Your Photo

Start from the Shot You Like

Keep working with your own portrait. This AI smile editor supports image uploads, so you can request an expression change without planning a new photo shoot.

Choose How Much You Smile

Ask for closed lips, a hint of teeth, or a warmer grin. Plain-language instructions give your AI smile filter a more specific direction.

Adjust More Than the Mouth

If the smile feels forced, use Chat Edit to request a smaller change to the mouth and cheeks. Review the eyes too, so the expression feels balanced.

Bring a Smile Reference

Upload another photo of yourself as a visual reference. Explain which photo to edit and which shows the smile you prefer.

Compare Subtle Variations

Request a gentle smile and a slightly broader version. Compare both at profile-picture size to choose the expression that suits your photo.

How to Keep an Added Smile Looking Natural

Add a small, closed-mouth smile to my uploaded portrait. Keep my facial proportions, skin texture, hairstyle, clothing, and background. Avoid extra teeth or beauty retouching.

👍

A convincing smile involves the mouth, cheeks, and eyes. Start small and compare with the original before asking for a stronger expression.

Use a Clear Face: Choose even lighting and a front-facing or slightly turned portrait. Blur, deep shadows, and covered lips make the edit harder.
Specify the Mouth: Say whether the lips should stay closed or teeth should show. A mild smile is a useful starting point for a professional headshot.
Check the Details: Look for odd tooth shapes, uneven lip edges, or eyes that no longer match the expression. Review skin texture and face shape too.
Keep a Reference: Compare against your original photo. If recognizable features drift, restart from it with a smaller expression change.

Small Fixes for Common Smile Edits

Closed-mouth smile: Edit my uploaded photo with a small smile and gently raised mouth corners. Keep the lips together and show no teeth.

Smile looks too wide: Reduce the grin in this edited photo. Relax the cheeks and keep the mouth closer to its shape in the original.

Teeth look artificial: Make the visible teeth less bright and less exposed. Avoid a uniform white strip, and keep the smile understated.

Eyes and smile do not match: Soften the smile and gently relax the eye area. Keep my eye shape and avoid an exaggerated squint.

Face looks different: Use my original portrait again. Add only a slight smile, retaining my facial proportions, age, and skin texture.

One person in a group: Add a subtle smile only to the person on the left in my uploaded photo. Keep the other faces and the setting unchanged.

Yes. Ask for a subtle, closed-mouth smile with no visible teeth. You can also ask to soften an existing grin or change an open-mouth smile to closed lips.

An expression edit can change nearby facial details. Ask to retain your features and compare with the original. Exact identity preservation and perfect teeth are not guaranteed.

Use a sharp, well-lit portrait with the face clearly visible. A front-facing or slightly turned face is easier to assess than a small, blurred, or heavily obscured one.

You can request an edit to a specific person, identified by position or clothing. Results vary, especially with small faces. Check every face afterward for unintended changes.

You can work in your browser without installing an app. Download the edited photo as PNG or JPG. Check the available export options before choosing your final file.
