How to Add a Smile to a Photo with AI

Add a smile to a photo with AI: prepare a clear portrait, choose a closed-mouth or toothy smile, write a short note and check the result against your original.

  1. Step 1. Upload one clear portrait

    Use one visible face with readable eyes, brows and lips. A front or gentle three-quarter portrait is a useful starting point. Upload JPEG, PNG or WebP, up to 30 MB.

  2. Step 2. Choose one expression reference

    Lift the mouth corners gently while keeping the lips together. Part the lips moderately and show a small natural amount of teeth. Keep the source portrait and select the smallest change that fits it. A template or upload supplies one expression reference; Extra notes clarify its strength. The source face remains the identity reference.

  3. Step 3. Generate the expression edit

    Check the displayed credits and click Generate. Each submission makes one static image. Selecting, uploading or removing a reference does not start generation. Add a short note for the expression's intensity, such as a small smile with lips together.

  4. Step 4. Compare and download

    Compare face shape, eyes, teeth, glasses, hairstyle, clothes and background with the original. Generative editing can change details. Reject an edit that no longer looks like the same person; keep the source and download only a result you have reviewed.

Choose a smile before writing extra notes

Keep the source portrait and select the smallest change that fits it. A template or upload supplies one expression reference; Extra notes clarify its strength. The source face remains the identity reference.

Choose a smile before writing extra notes

Closed-mouth smile
Lift the mouth corners gently while keeping the lips together.
Useful when the original hides the teeth; compare cheeks and eyelids.
Toothy smile
Part the lips moderately and show a small natural amount of teeth.
Newly exposed teeth are generated details. Inspect their shape and alignment.
Laugh
Open the mouth and let the cheeks and eyes react together.
A stronger edit changes more facial detail; keep the head angle steady.
Uploaded expression reference
Use a face with a similar viewing angle and the desired smile.
Only its expression is a guide. Its identity, hair, style and background are not the subject.

Short extra-note examples

Small smile
A small closed-mouth smile; keep the original face, skin texture and scene.
The lips stay together and the eyes remain natural.
Friendly headshot
A moderate friendly smile, with only a little upper teeth showing. Keep the head angle and outfit.
Compare the visible teeth, glasses, jaw and jacket.
Reduce an exaggerated smile
Keep the chosen smile subtle. No wide laugh, no change to the background or lighting.
If it still looks too strong, start from the original with the closed-mouth template.

Check the face as well as the expression

View the result at full size beside your source. A believable expression should fit the same person and the same photo or artwork.

Identity and texture
Compare the nose, jaw, age, skin texture, hair, glasses and facial hair. A reference should not replace the person.
Use a sharper source and ask to retain the original face and texture.
Eyes, lips and teeth
Look for mismatched pupils, doubled eyelids, unnatural lip edges or invented tooth shapes. A wider smile exposes more detail to inspect.
Try a smaller closed-mouth smile or an expression reference closer to the original face angle.
Original scene
Compare the body pose, head direction, outfit, light and background. The expression request should not become a new portrait or pose.
Choose a reference with a similar head angle and ask to keep the original framing and scene.
Expression strength
Match the expression to the intended use. A small closed-mouth smile often needs fewer changes than an open-mouth laugh.
Write one intensity instruction; remove conflicting notes and start again from the original.

Questions about adding a smile

What is a good first attempt?

Choose the gentle closed-mouth smile and keep Extra notes short. It requests a smaller change and does not need newly visible teeth.

Can AI recover my exact teeth from a closed mouth?

A photo with closed lips does not show the teeth. An open-lip result contains generated detail, so compare it carefully rather than treating it as a faithful reconstruction.

Why did the reference change my face?

The reference is intended to guide expression only, but generation can drift. Use a clearer source, a similar-angle reference and a smaller smile; reject a result with the wrong identity.

How do I try again without editing the generated face repeatedly?

Use Re-edit to restore the original Person image and expression settings, then change one reference or note. Keeping the original avoids stacking several expression edits on an already changed face.
