Real-ESRGAN Super Resolution Technology

Enhance image resolution by 4x while preserving fine details and reducing compression artifacts.

4x Image Upscaling

Enhance resolution by 4x while preserving detail and sharpness. Real-ESRGAN transforms low-resolution images into high-quality assets suitable for print, displays, and professional use without losing critical visual information.

Noise Reduction

Remove compression artifacts, grain, and noise during upscaling. The AI model intelligently identifies and eliminates unwanted visual noise while enhancing genuine image details for cleaner, more professional results.

Face Enhancement

Dedicated face restoration for portrait upscaling with natural results. Real-ESRGAN includes specialized models trained specifically on facial features to restore and enhance portraits without artificial over-smoothing.

Batch Processing

Upscale hundreds of images in a single API call. Process entire image libraries efficiently with automated batch operations, perfect for e-commerce catalogs, photo archives, and large-scale content workflows.
