What is ON1 Resize AI 2026

ON1 Resize AI is a standalone photo enlargement and image upscaler for PC and Mac. As a standalone application, you can use ON1 Resize AI independently of your favorite photo editor or as a plug-in for photo editors such as Lightroom Classic, Photoshop, and Capture One.

ON1 Resize AI 2026’s interface is concise, straightforward, and responsive.

ON1 Resize AI will cost you a one-time payment of US$99.99 for a lifetime license. You can also acquire Resize AI as part of ON1 Photo Raw. However, at this time, ON1 Photo Raw is equipped with the much older and less effective Resize 2023.5. Buy ON1 Resize AI Now

What does ON1 Resize AI do?

ON1 Resize AI is an AI-powered image upscaler that you can use to enlarge your digital photographs. Unlike traditional photo enlargement functions that blindly turn one pixel into many, ON1 Resize AI uses Artificial intelligence to anticipate and insert additional detail into your upscaled image.

ON1 Resize AI 2026 before and After test
ON1 Resize AI 2026’s upscaling is among the best in class.

As a result, photos enlarged with Resize AI are not only larger but potentially more detailed than the smaller original. Therefore, you might use Resize AI to enlarge photos taken with older low-resolution cameras or to upscale an already large image to create a giant print.

Regarding printing, ON1 Resize AI 2026 comes equipped with hundreds of presets, each of which is optimized for different printers and paper qualities. You can use Resize AI’s crop tool to recompose your photo, exploit its excellent focus-correcting sharpening tools, and even add a little film grain.

Resize AI also offers a Tiling feature, which enables you to split a single image into as many parts as you like – ideal for creative prints and carousels on Instagram. Meanwhile, you can use the Gallery wrap feature to prepare your image to be printed onto a canvas frame. Download ON1 Resize AI Free Trial

Who is ON1 Resize AI for

ON1 Resize AI is suitable for anyone looking to enlarge their collection of smaller photos or to turn a large image into a giant print. Compared to upscaling alternatives such as Gigapixel, Resize AI’s print-friendly feature set is incredibly appealing – particularly the Tiling and Gallery wrap features, as well as the ability to use and create presets.

What is new in ON1 Resize AI 2026

ON1 Resize AI 2026 features vastly improved AI upscaling models delivering superior results compared to the previous version, ON1 Resize 2023. Specifically, you can choose between a light-weight AI model for faster results or a slower model that prioritises image quality. You can also specify whether your photo is of standard or high quality, and Resize AI will react accordingly.

ON1 Resize AI 2026 vs 2023
ON1 Resize 2026’s AI upscaling models are vastly superior to those of Resize AI 2023.5.

Otherwise, Resize AI 2026 is similar to its 2023 predecessor. But since the improvements to image quality are so vast, I consider Resize AI 2026 an essential upgrade. Upgrade to ON1 Resize AI 2026 Now

Is ON1 Resize AI any good

How I test Upscalers

I begin with a reference image and then shrink it fourfold to create a one-quarter-sized copy. Next, I upscale the one-quarter-sized copy by 400%, thus restoring the copy to its original dimensions. Finally, together we compare the upscaled image with the identically sized reference image to see how faithful the upscaled copy is.

Image quality

ON1 Resize’s new AI models place it into the top tier of AI upscalers by vastly outperforming mid-tier alternatives like Lightroom’s Super Resolution, Luminar Neo’s Upscale AI, and ACDSee’s Super Resolution.

ON1 Resize AI 2026 vs Lightroom
ON1 Resize AI outperformed Lightroom Super Resolution in all of my test cases.

However, both Topaz Photo AI and Gigapixel continue to give Resize AI a hard time. This is particularly apparent in my portrait test, where Gigapixel and Photo AI’s lighter touch produces a more natural-looking result. In contrast, ON1 Resize AI’s output was comparatively harsh, though I was able to soften the result using its Face Recovery feature.

My Lighthouse photo has proven to be very difficult to upscale. While Resize AI’s effort is better than many, it still falls well short of the original image and Photo AI and Gigapixel’s output.

ON1 Resize AI vs Gigapixel
My Lighthouse photo is tough to upscale. However, Gigapixel and Photo AI get closer to a usable result than ON1 Resize AI.

Finally, I wanted to find out how Resize AI handled a poor-quality, noise-ridden image, and the results were stunning. Specifically, Resize AI delivered an image that was not only much larger but also cleaner and sharper than the original. Moreover, the result was vastly superior to that of Gigapixel 8 and comparable to Topaz Photo AI, an all-in-one image application that costs twice as much.

ON1 Resize AI vs Gigapixel
Gigapixel struggles to upscale noise-ridden photos, whereas ON1 Resize AI seems to get better as image quality grows worse.

Overall, ON1 Resize AI is comparable to the best upscalers. In some cases, it will fall short of Gigapixel and Topaz Photo AI, and other times, it may exceed them both. Therefore, I strongly recommend you test ON1 Resize AI for yourself, using your files and your computer. Test ON1 Resize AI – for Free

Is ON1 Resize AI good for beginners?

ON1 Resize AI’s interface is concise, straightforward to use, and easy to become acquainted with. Moreover, it’s hugely responsive and its render times are quick – even when using its slower high-quality AI upscaling models. While I wish Resize AI included a one-click automatic mode, this can be mitigated by using and creating presets. Meanwhile, applying your enhancements to an image is a breeze. Overall, ON1 Resize AI is a delight to use.

Alternatives to ON1 Resize AI

The most compelling alternative to ON1 Resize AI is Gigapixel. When it comes to common upscaling, both are similarly excellent, though one will be better than the other depending on the photo. For instance, Gigapixel did a better job upscaling my Portrait and Lighthouse photos, but Resize AI did better when it came to enlarging my Bellbird and Furseal images. Read Gigapixel Review

ON1 Resize AI vs Gigapixel
Depending on the photo, ON1 Resize AI has the means to outperform Gigapixel and vice versa.

Image quality aside, ON1 Resize AI offers print-friendly features such as Tiling and Gallery wrap, whereas Gigapixel does not. However, Gigapixel offers intermittently effective generative AI features such as Recover and Redefine, which can produce excellent results, sometimes, so long as you’re willing to wait an age for a local render, or pay an additional cost to render it more quickly in the cloud.

In terms of upscaling, I still consider Topaz Photo AI the most flexible. Specifically, Photo AI can upscale, denoise, and deblur simultaneously. However, Resize AI came extremely close while costing half as much. Read Topaz Photo AI Review

ON1 Resize AI vs Lightroom
ON1 Resize AI 2026 is compatible with Lightroom Classic and Photoshop, and it outperforms Adobe’s Super Resolution upscaler.

If you are already using Lightroom, ON1 Resize AI represents a significant upgrade over Adobe’s Super Resolution. But you can use Resize AI as a plugin for Lightroom Classic and Photoshop. Buy ON1 Resize AI Now

Conclusion

ON1 Resize AI 2026 is a top-tier upscaler that vastly exceeds its predecessor, Resize 2023, and rivals such as Lightroom Super Resolution, Luminar Upscale AI, and ACDSee Super Resolution.

Photo Sharpening with ON1 Resize AI 2026
ON1 Resize AI excels at sharpening slightly blurred photos.

However, Gigapixel and Photo AI can still outperform Resize AI when it comes to upscaling some images. Equally, Resize AI can outperform Gigapixel. For example, Resize AI left Gigapixel in its wake and came remarkably close to exceeding Topaz Photo AI when upscaling my noise-ridden image of a Bell Bird.

Therefore, when choosing between Resize AI, Gigapixel, and Photo AI, you might consider factors like price and feature set. For instance, Resize AI costs the same as Gigapixel and half as much as Photo AI. You may also prefer Resize AI’s array of print-friendly features, such as its Presets, Tiling, and Gallery Wrap tools. Yet those of you interested in generative AI, flawed as it may be, might prefer Gigapixel.

Regardless, ON1 Resize AI is an excellent upscaler that combines top-tier results with a print-friendly feature set and wraps it all up in a responsive and easy-to-use interface. Therefore, I strongly recommend you give it a go. Try ON1 Resize AI now – for Free | Buy ON1 Resize AI Now
