What is an AI Image Upscaler?
An AI image upscaler uses advanced machine learning models to increase the resolution of images while preserving important details. Unlike traditional resizing methods that stretch pixels and reduce quality, AI-based upscaling intelligently reconstructs missing details. This results in sharper, clearer, and more natural-looking images, even when starting from low-resolution or blurry inputs.
