1. What is Face Changing?
Face changing is the process of digitally transforming or replacing a person’s face in an image or video using AI. It combines techniques such as face swap, face replacement, expression re-targeting, and identity anonymization to create realistic, context aware visuals. These techniques can modify identity while preserving the original lighting, skin tone, and facial expression for seamless results.
Common applications of face changing include creating viral content for social media, generating consistent model visuals for Ecommerce, producing editorial composites for fashion and media, and building anonymized datasets for research and AI training.
AI plays a crucial role by automating complex manual editing steps like color blending, facial alignment, and texture preservation. Instead of manually adjusting each image, AI models handle these details with near human precision, drastically improving turnaround time and quality.
Insert face changing tools often prioritize entertainment and instant results, while production tools like PiktID focus on control, precision, and trust — essential for professional grade creative teams and brands managing identity sensitive projects.

Canva doesn’t offer identity reuse, anonymization, or batch level editing capabilities — making it insufficient for large scale face changing operations, such as fashion look books or marketing pipelines.
DeepSwap.ai provides strong realism and supports both photo and video swaps, appealing to professionals who need accurate face changing results. Its deep learning models produce impressive likeness and emotion retention. However, DeepSwap’s subscription model and lack of ethical and privacy transparency have raised concerns. Brands seeking compliant workflows or anonymized identity handling cannot rely on this tool for GDPR-safe use cases.
Pixlr (web editor):
Pixlr is a quick, web based editor that makes casual face changing accessible to anyone. Its drag and drop simplicity suits hobbyists or marketers working on one-off images. However, Pixlr doesn’t support enterprise APIs, identity storage, or lighting consistency tools — essential for campaigns that require brand level precision.
Other web tools and hobbyist editors:
Numerous online tools offer instant AI face changing, but their results are inconsistent. Artifacts, hairline mismatches, and tone disparities often reduce output quality. These tools prioritize speed over control and don’t provide the data security or scalability businesses demand.
Choosing the right tool for you
Most top consumer tools excel at speed, accessibility, and virality — perfect for entertainment, but not production. PiktID’s AI photo face swap fills this gap by combining identity storage, anonymization, API integration, hair flag control, and batch swap functionality. This makes it the preferred choice for creators, Ecommerce brands, and studios who need precise, ethical, and repeatable AI-driven face replacer across campaigns and catalogs.

5. Step-by-Step: How to Change a Face in Photos
This section explains exactly how to use PiktID’s AI tools for seamless face changing in photos — without any technical setup or coding. It’s designed for content creators, Ecommerce teams, or studios looking to enhance visuals with professional grade face replacement and identity management.
A. Prep: Capture & Choose Images
Before starting the face changing process, the quality and alignment of your images matter most.
- Target image (the photo where you’ll replace the face):
Use a clear, well lit image with minimal shadows or obstructions (avoid sunglasses or heavy accessories). The best results come from frontal or ¾ angle shots where the face is clearly visible.
Tip: Choose images at least 1024 × 1024 resolution for sharper results. - Source face (the image whose face you want to apply):
Match the expression and angle as closely as possible to the target. For example, if the target subject is smiling slightly and facing right, use a source photo with similar lighting and expression.
This alignment ensures the AI produces a natural and photo realistic face changing result.
B. Upload & (Optional) Anonymize
- Go to PiktID Studio → Swap Tool.
- Click Upload Target Image to import your main photo.
- (Optional) Run Anonymize — this replaces the original face with a synthetic identity.
- Why this matters:
- Privacy: Protects the identity of real people while allowing full editing control.
- Consistency: You can store these synthetic identities and reuse them across future sessions for consistent branding or model reuse.
- Why this matters:
Using Anonymize before starting the face changing process helps maintain compliance with data protection norms while enabling creative freedom.
C. Upload or Select Identity
Next, decide which face you want to apply:
- Upload a new source image:
Simply drag and drop an image containing the desired face. - Or select a stored identity:
If you’ve previously created synthetic models using the Anonymize tool, choose one from your Stored Identities Gallery.
This allows quick and consistent face changing across multiple campaigns, shoots, or Ecommerce listings — perfect for scaling creative work flows.
D. Configure Generation Options
Fine-tune the face changing process to get realistic, production grade results.
- flag_hair:
Set to “true” to blend hair and head features from the source face. Set to “false” if you want to retain the target’s hairstyle. - prompt_strength / similarity:
Adjust between 0.6 – 0.9 to control how closely the output follows the source identity versus the original image. Lower values keep more of the target image; higher values make a stronger swap. - seed:
Use a seed number for repeatability — this ensures that multiple generations of the same parameters yield consistent outputs. - watermark (Pro feature):
Toggle watermark settings for client or internal review stages.
Example configuration prompt:
{
"flag_hair": true,
"prompt_strength": 0.85,
"seed": 42
}
This setup produces balanced, natural face changing results while retaining environmental realism.
E. Generate, Review, Iterate
Once settings are in place:
- Click Generate — PiktID’s AI will process the face changing operation within seconds.
- Review your results in the History tab.
- Use quick troubleshooting if needed:
- Hair halo or edge blur: Try lowering prompt_strength slightly or enable flag_hair.
- Skin tone mismatch: Re-upload both images with similar lighting or use post generation tone correction.
- Expression distortion: Ensure both images share a similar expression and angle.
Iterate as needed to achieve the perfect natural look. Every generation is logged for easy side by side comparison.
F. Export & Housekeeping
Once satisfied with your face changing results:
- Click Download to export the final image.
- Review temporary retention policies — generated files are stored briefly for user access but should be downloaded for long-term use.
- Save key versions in organized folders by project, model identity, or campaign.
For teams managing multiple projects, maintaining a consistent naming convention helps track outputs efficiently.
