What’s an AI Image Upscaler

Upscaling a photo means enlarging the photo dimensions (width and height) and size. Traditionally, photo editing software just stretches the pixels, which might lead to blurry or low-quality results.

AI image upscalers are the complete game changer. They are trained on massive datasets containing pairs of low-resolution and corresponding high-resolution images. Based on the trained resources, AI learns the patterns, the textures, the details, and what sets high-quality images and lower-resolution images apart.

Whenever a lower-resolution image is uploaded, AI image enhancers will first try to understand the image structure first, predict the value of new pixels and reconstruct high-frequency details, resulting in sharper, more detailed images.
