Build for upscaling AI images.
Pro Upscaler is the only upscaler designed specifically for Al-created images. No weird textures. No synthetic grain. Just clean, production-ready output up to 105MP (starting from images up to 20MB).
Clean results, every time.
Go beyond surface-level fixes, Pro Upscaler reconstructs fine details and natural structures, delivering images that are sharper than ever before. Mention Creative and Precise Mode.
Stay in your flow.
Upscale and enhance directly in your workspace. No downloads, no uploads. No switching tools. Just crisp images.
Precise Mode
Select Precise to retain strict fidelity to your original image. Activate the Fix AI Image Artifacts toggle to clean the AI noise that other upscalers miss.
Creative Mode
Choose Creative to repair imperfections and reconstruct complex details. Set the creativity strength to subtle, balanced, or strong to achieve the result you need.
FAQS
What is image upscaling?
Image upscaling increases the resolution and overall size of an image. The process adds pixels to a smaller image so you can print it at large scales or display it on high-resolution screens without pixelation.
How does AI image upscaling work?
Instead of simply stretching the available pixels, AI upscalers like Leonardo’s Pro Upscaler predict and reconstruct missing details, textures, and edges. This approach produces a sharp, high-definition result.
How do I upscale an image without losing quality?
To avoid losing quality, use a dedicated AI upscaler rather than standard resizing tools. Standard upscalers cause blurriness because they stretch existing pixels, whereas AI tools like Leonardo’s Pro Upscaler reconstruct missing detail rather than stretch them.
How do I upscale AI-generated images?
To upscale AI-generated images, use a tool designed exclusively for AI images, like Leonardo’s Pro Upscaler. Because standard upscalers are built for real photos, they typically amplify AI artifacts rather than eliminate them.
Can I upscale images 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.
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 Leonardo.Ai upscale images to 4K?
Yes, Leonardo.Ai can upscale images to 4K, and it goes much further. Leonardo’s Pro Upscaler delivers a true 105 MP that easily outperforms any 4K upscaler. A true 105MP output covers almost every professional use case with total clarity, from social media thumbnails to large-scale 8K displays and billboards.
Is 4K or megapixels (MP) better for measuring upscaled image quality?
Megapixels (MP) provide a more accurate measure of true image size and detail. "K" refers to the number of pixels along the longest edge of an image, so a 4K image has roughly 4,000 pixels on its longest side. Megapixels (MP) refers to the total number of pixels across the entire image, measured in millions. You find the MP count by multiplying the width by the height and dividing by one million. Because still images have much more varied aspect ratios, "K" isn't a reliable figure for images unless an exact aspect ratio is specified.
What is the difference between AI upscaling and traditional upscaling?
Traditional upscaling simply duplicates or stretches existing pixels, which creates blurry edges and blocky textures. AI upscalers like Leonardo’s Pro Upscaler analyze the image context and generate new pixels. They rebuild complex textures and repair flaws, which results in a sharp, production-ready image.
