How it works
Upload your photo
Drop your portrait into EditThisPic. Front-facing photos with clear visibility of the mouth and eyes work best. The AI needs to see the full face to adjust expressions naturally. JPG, PNG, WebP up to 7MB.
Describe the smile you want
Type your instruction: 'add a natural happy smile showing teeth' or 'add a soft gentle smile with closed lips.' Specify the type of smile - big and joyful, subtle and warm, or professional and confident. The AI adjusts the entire face naturally, including the eyes, for authentic expressions.
Copy one of these to get started:
add a warm natural smile with teeth showing, genuine happy expression with smiling eyes
add a subtle confident smile with closed lips, professional and approachable expression
add a big genuine smile with a wide grin showing teeth, joyful expression with laughing eyes
add a soft gentle smile with slightly upturned lips, warm and friendly expression
3 more prompts
add a playful happy smile with teeth showing, childlike joy and bright eyes
replace the forced smile with a more natural relaxed smile, genuine expression
add a warm graceful smile appropriate for an older adult, dignified and pleasant expression
Generate and review
Check that the smile looks natural and not forced. Look at the eyes - real smiles create crow's feet. Verify the expression matches the person's face structure and doesn't distort their features.
Refine intensity if needed
If the smile looks too big or too subtle, adjust with follow-up prompts: 'make the smile slightly more subtle' or 'increase the smile to show more teeth.' Fine-tuning gets the exact expression you want.

If something looks off
Smile looks fake or forced
Why: The AI adjusted only the mouth without changing the eyes and cheeks, creating an unnatural expression.
add a genuine natural smile with smiling eyes and raised cheeks, full facial expression change
💡 Real smiles engage the whole face. Always mention 'smiling eyes' or 'genuine expression'
Teeth look strange or unnatural
Why: The AI-generated teeth don't match the person's natural teeth or look too perfect.
add a natural smile with realistic natural-looking teeth, or use closed-lip smile
💡 Closed-lip smiles avoid teeth generation entirely and often look more natural
Face shape appears distorted
Why: The smile transformation stretched or compressed facial features unnaturally.
add a subtle natural smile that preserves the face shape and proportions
💡 Start with subtle smiles and increase intensity gradually rather than jumping to big grins
AI changed the wrong area or something I didn't want changed
Why: The AI could not determine exactly which area you meant from description alone. This happens with ambiguous requests.
Tap a marker on the specific area you want to change, then regenerate with the same prompt
💡 Markers tell the AI 'I mean THIS one specifically.' Use them when description alone is ambiguous.
Expression doesn't match the photo context
Why: The smile type is inappropriate for the setting or photo mood.
add a [subtle/warm/professional] smile appropriate for [context - formal/casual/family]
💡 Match smile intensity to the photo context - subtle for professional, bigger for casual
Quick answers
Do I need to mark the face before adding a smile?
No! Just describe the smile you want: 'add a warm natural smile' or 'add a subtle smile with closed lips.' The AI automatically detects the face and adjusts the expression. Use markers only if you need to adjust a specific person in a group photo.
Will the smile look natural and not creepy?
When you include 'genuine' or 'natural' and mention 'smiling eyes' in your prompt, the AI adjusts the entire face - not just the mouth. Real smiles involve crow's feet at the eyes and raised cheeks. Subtle smiles tend to look more natural than exaggerated grins.
Can I add a smile to someone who looks angry or sad?
Yes, but extreme expression changes may need multiple refinements. Start with a subtle smile and increase gradually. Very dramatic expression changes (angry to beaming) are harder to make look natural than neutral to smiling.
Does this work on group photos?
Yes. The AI can add smiles to multiple people. For control over specific individuals, tap a marker on the person you want to adjust. You can also process each person separately with different smile types.
Can I adjust the intensity of the smile?
Absolutely. Use terms like 'subtle,' 'gentle,' 'warm,' 'big,' or 'wide' to control intensity. If the first result is too much or too little, follow up with 'make the smile more subtle' or 'increase the smile slightly.'
