CodeFormer

"CodeFormer is a powerful and easy-to-use AI tool designed to restore faces in old, blurry, or AI-generated images. Developed by researchers at Nanyang Technological University, it uses a smart transformer model and a visual “codebook” to fill in missing facial details while keeping the original vibe. You can adjust a simple slider to choose whether you want sharper quality or closer resemblance to the original image.

Features:

Transformer-based restoration: Uses smart AI to predict face details based on the full context of the image for better, natural results.

Visual codebook knowledge: Refers to a library of real face features to add fine details without guesswork.

Adjustable fidelity slider: Lets you decide if you want sharper faces or more accurate likeness by tweaking one slider.

Background enhancement: Optional tools can clean up and sharpen the photo’s background for a polished look.

Use Cases:

Fix old family photos: Restore grandparent pictures from the past and bring their faces back to life.

Enhance AI-generated faces: Improve blurry or glitchy faces from AI art tools like Stable Diffusion.

Clean tourist snapshots: Sharpen and restore fuzzy travel photos of yourself or friends.

Strengthen project visuals: Use in school or history projects to improve image quality and storytelling.

With CodeFormer, you get a powerful AI that makes face restoration simple—no technical knowledge needed, just choose an image and let it work its magic."
