Frequently Asked Questions
How does AI upscaling work?
The AI model has been trained on millions of images to understand patterns, textures, and details. It uses this knowledge to intelligently fill in new pixels when enlarging an image.
Is the quality really better than regular resizing?
Yes, significantly. Regular resizing just interpolates between existing pixels, producing blurry results. AI upscaling generates realistic new detail.
What images work best?
Photographs and natural images upscale best. The AI understands faces, landscapes, textures, and objects well.
