Here is the complete guide to convert your Selfie or image to a professional passport-size image

AI photo editing is a double-edged sword: it can turn a bedroom selfie into a professional headshot in seconds, but it often has the frustrating habit of turning you into a “weird cousin” you don’t recognize.

In 2026, generative AI models like GPT-5.2 and Nano Banana have made huge strides, but they still struggle with “identity drift.” Here is a breakdown of why this happens and how you can stop the AI from rewriting your DNA every time you want to change a background. Here is the prompt you need to give first, so don’t change the face.


Use the uploaded reference image as the permanent facial identity reference.

Face Lock (Highest Priority):
The person’s face must remain 100% identical to the reference image. Preserve all facial features exactly, including facial structure, proportions, skin tone, eye shape, eye distance, eyebrows, nose shape, lips, jawline, cheekbones, and any unique facial details.

Do NOT modify, beautify, stylize, age, smooth skin, sharpen features, or reinterpret the face. Do NOT generate a similar-looking person. It must clearly be the exact same individual.

Identity Consistency Rule:
Across all generated images, the face must remain consistent and recognizable as the same person. If the face becomes distorted, unclear, partially hidden, or altered, regenerate the image using the reference face instead of changing the identity.

Allowed Changes:
Only the following elements may vary:
- Pose
- Camera angle
- Clothing
- Hairstyle (optional)
- Lighting
- Background
- Environment
- Color grading

Face Stability Requirements:
- Maintain identical facial proportions
- Maintain identical eye shape and spacing
- Maintain identical nose and lip structure
- Maintain identical skin tone and texture
- Preserve natural facial asymmetry

Technical Quality:
Photorealistic image quality with natural lighting and realistic skin detail. No cartoon, illustration, painting, or stylized rendering unless explicitly requested.

Final Rule:
Facial identity preservation is the highest priority. Every generated result must look like the same real person photographed in different situations, not a variation or reinterpretation.

Prompt Passport size pic

Could you copy the prompt and then upload your selfie or any picture you want to convert into a passport-sized pic?

The prompt is below.

Pro Strategies to Keep Your Face “Locked”

If you are tired of the AI playing plastic surgeon, use these technical “identity-lock” tricks:

1. The “Identity-Lock” Prompting

Generic prompts lead to generic faces. Use high-precision language to force the AI to respect your features:

The “Landmark” Clause: Add: “Preserve original facial landmarks, bone structure, and skin texture exactly.”
The “Negative” Guard: Use negative prompts like: “[Avoid: facial distortion, skin smoothing, altered eye shape, plastic texture, bloated cheeks]”.
The Reference Anchor: Explicitly state: “Keep the face 100% identical to the uploaded reference image; only modify the [background/outfit].”

2. The “Strength” Setting (Denoising)

If you are using tools like Stable Diffusion or Fooocus, the “Denoising Strength” is your most important slider.

Setting it to 0.4 or higher: The AI will likely change your face.
Setting it to 0.1 – 0.2: The AI stays extremely close to the original pixels. This is the “sweet spot” for changing a shirt while keeping the face untouched.

3. Use Inpainting (Masking)

Don’t let the AI touch your face at all.

Use a Masking Tool to highlight only the areas you want to change (like your hair or clothing).
By “masking out” your face, you tell the AI that those pixels are off-limits for editing.

Recommended Tools for Face Consistency

If you need high-fidelity results without the “AI-look,” these specialized tools are currently leading the market:

Nano Banana Pro: Specifically optimized for realistic skin textures and identity retention.
FaceApp / Remini: Still the kings of “one-tap” edits that maintain your actual likeness.
EraseID / PiktID: Professional-grade tools designed to change expressions or outfits without altering the person’s identity.
