About the Image Upscaler (Enlarge & Sharpen)
Make small images bigger for printing, presentations or websites. The image is enlarged in several high-quality steps (which keeps edges smoother than one big jump), then an adjustable unsharp-mask restores crispness. This is classic upscaling, not generative AI, so it won't invent new detail — but it gives clean, natural results without artificial textures.
