ON1 Resize, powered by Genuine Fractals, has been the gold standard for photo resizing and preparing your photo’s final output, and it has been for over twenty years. ON1 Resize AI (coming in April) is the most significant improvement we’ve made to photo enlargement software since the early days of Genuine Fractals. Resize AI uses state-of-art machine learning to create the details and sharpness that get lost when you enlarge a photo. It goes beyond just keeping the edges sharp. It interprets elements in your photos and, in some instances, can create details to keep your enlarged images looking clean and crisp. It’s incredible!

Pre-order ON1 Resize AI.

In the past, interpolation methods were used to add new pixels to photos to make them bigger. You simply can’t stretch an image to be bigger without adding pixels, or the photo becomes pixelated in appearance.

When Genuine Fractals (and the following ON1 Resize) was introduced, it changed interpolation by using the power of fractals. This method creates a scalable skeleton of the photo to help maintain sharper edges, even though it still uses bicubic for the smooth and textured areas. This was much better over the traditional bicubic method, but the original information in the photo still limited the results it could produce. ON1 Resize AI solves the problem of creating new, believable details and pixels at scale. You will also have complete control over the sharpness of your results.

We train ON1 Resize AI by showing it millions of examples of photos. We can teach it to see textures like rocks, skin, fur, feathers, masonry, tree bark, etc. Then, it learns how to recreate these textures and make them look realistic in the upscaled photos. Check out these examples below.


Gorilla Example

The above example started as a raw file from a Nikon D200, an older camera. The original photo is only 2580×3857. We scaled it only 2x to make a print size of 17″ x 26″. This is an excellent example of how you can breathe new life into your old photos or mobile photos. In this comparison, we include a comparison with another popular AI-based interpolation app.


Leaf Example

The above example also starts as a Canon raw file. We interpolated it just 2x, a typical range for most photographers, to see the difference you would get. It’s pretty striking when you see the difference in detail. In this example, we also compared the Genuine Fractals algorithm and Adobe’s latest super-resolution-based method.


Portrait Example

The above example is another stock JPG image, interpolated 2x. I wanted to show a portrait photo to see how Resize AI balances details like hair and eyelashes with subtle details like skin. In this comparison, you can also see the standard bicubic and another popular AI-based interpolation app.


Castle Example

The above example is a stock image JPG. You don’t always have the luxury of starting with a raw file. This example has been sharpened and processed before we resized it and has some JPG artifacts from the compression. We scaled it 2x to a comfortable poster-print size. You will note how Resize AI removes the JPG artifacts while increasing the sharpness of the edges and bringing back the subtle detail in the brick. When you compare it to Genuine Fractals, you can see just how superior the new version is to the old.


Castle Example

The above example starts as a raw file from a Canon 5D MK II. Originally it was 5616×3744 pixels and would make a print almost 13″ x19″. We scaled it up 4x to make a print over 70″ long. Granted that it is bigger than many of us may make, I chose it to illustrate the point that Resize AI can create new details, guided by the original detail from the photo. If you look at the bicubic interpolated version, you will see how soft the photo is and how much detail is lost. When you compare that to Resize AI you can see the details in the rocks and the individual trees.

ON1 Resize AI is the perfect solution for cropping a section out of your photo if your lens can’t get you close enough or preparing and printing your biggest and best photos. It can crop, resize, and sharpen all at once. It can add wings for printing on canvas or create tiles for a mosaic. You can also batch process images and print them right from the app. You will be amazed by what you can do with ON1 Resize AI. ON1 Resize AI works as a plugin for Adobe Lightroom, plugin for Adobe Photoshop, and plugin for Capture One. Resize AI goes beyond the average plugins. In CaptureOne and Lightroom you can batch process easily with powerful new resizing options. And in Adobe Photoshop it can handle layered files with masks, alpha channels, text, and adjustment layers in RGB as well as CMYK, Grayscale and LAB.
