Featured
Pro
Our flagship, state-of-the-art upscaler. Choose Precise to preserve exact detail with clean or detailed enhancement, or Creative to generate new detail as you upscale — up to 8x and a true 105-megapixel output.
Ultra
Fine-grained control over creativity, detail contrast, and similarity, with Realistic or Artistic style presets to match any image.
Alchemy
Refine and upscale generated images with controllable strength and a creative mode for smooth, clean results — right in your generation flow.
FAQS
What is an AI upscaler?
An AI upscaler increases an image's resolution using machine learning. Instead of stretching existing pixels like traditional resizing tools, it predicts and reconstructs missing detail, texture, and edges to produce a sharp, high-resolution result.
Which AI upscalers does Leonardo offer?
Leonardo's upscale model picker offers a growing lineup: Pro, our flagship, with Precise and Creative options and true 105-megapixel output; Ultra, with fine-grained control over creativity, detail contrast, and similarity; and Alchemy, for refining images right in your generation flow. As new state-of-the-art upscale models emerge, they join the lineup — so the best available upscalers always live on Leonardo.
What is the best AI upscaler for AI-generated images?
Leonardo's Pro Upscaler is built specifically for AI-generated images. Standard upscalers are designed for real photos and tend to amplify AI artifacts, while the Pro Upscaler recognizes and cleans them as it upscales to a true 105MP.
Can I upscale images with AI for free?
Leonardo.Ai provides a daily allocation of free tokens that you can use to upscale your images. However, to access the Pro Upscaler at the maximum 8x magnification, you need a premium subscription.
How do I upscale an image without losing quality?
Use a dedicated AI upscaler rather than a standard resizing tool. Standard tools cause blurriness because they stretch existing pixels, whereas an AI upscaler like Leonardo's Pro Upscaler reconstructs missing detail for a crisp result at any size.
Can the AI upscaler enhance real photos as well as AI images?
Yes. The upscaler adapts to the format of your image, whether it's a photograph, digital artwork, or an AI generation, and reconstructs detail appropriate to that format.
What image formats can I upscale with Leonardo.Ai?
You can upload and upscale standard formats like JPG, PNG, and WebP. The upscaler also works directly on any image you generate natively within the Leonardo platform.
Can I upscale images to 4K or 8K?
Yes. Leonardo's Pro Upscaler delivers a true 105MP output, which goes well beyond 4K and covers professional use cases from social media thumbnails to 8K displays and billboard print.
What is the difference between AI upscaling and traditional upscaling?
Traditional upscaling duplicates or stretches existing pixels, which creates blurry edges and blocky textures. AI upscaling analyzes the image context and generates new pixels, rebuilding complex textures and repairing flaws for a sharp, production-ready image.
