What is Nero AI Image Upscaling?

Whether you’re a blogger or designer, an online store owner, or a student, poor photo quality can be a major obstacle when it comes to photo printing and sharing.

These problems are now things of the past – with Nero’s cutting-edge deep learning technology, you can now enlarge your photos by enhancing their details and increasing their resolution.

What is Nero AI Image Upscaler (Lens)?

Nero AI Image Upscaler (Lens) is an AI-powered tool that can enlarge image size and increase resolution with enhanced quality.

By reducing noise and sharpening the details, AI Image Upscaler (Lens) lets works best on small images and photos.

How does Nero AI Image Upscaler (Lens) work?

Nero AI Image Upscaler (Lens) uses state-of-the-art image super-resolution technology based on deep convolutional neural networks.

Our neural network is trained on an immense dataset of training photos. In detail, we used millions of low-resolution and high-resolution image pairs to train the software on upscaling images and to learn typical features of physical objects such as the bricks of walls, hair and skin.

After the network recognizes those features on the images, it will enhance those details based on its general knowledge of the world.

What is traditional image upscaling?

Before AI-based image upscaling technology, it was virtually impossible to increase photo or image size without losing quality.

The best option, called Bicubic Interpolation – made your image unsharp and blurry.

What pictures work best with Nero AI Image Upscaler (Lens)?

The system works best with unprocessed images that were not previously upscaled or pixelated by any other software tool.

Our main focus currently is upscaling physical content with sharp corners like digital illustrations, images with sharp borders, and contrasting textures (such as watches).

For images with small human faces or text, the result will be less obvious after processing.

Do you remove JPEG compression artifacts?

Yes, we automatically remove JPEG noise (also known as compression artifacts), if we detect an image with a .jpg or .jpeg extension.

If for any reason you want to upscale your image without removing noise, you can input your image as a png-file.

Is there a size limit for the images I want to upscale?

Users of the online version can use images with 3.75 megapixels (e.g. 2560*1440 pixels in 16:9).

Users of the mobile version which is called “Nero Lens” can use images with¬†4032*2268¬†pixels in size.

For the desktop version, the source image should be smaller than 16.78 megapixels.

However, the processing speed depends on your desktop’s or mobile’s CPU and GPU limitations.

Processing a high-resolution image will take up more time. In addition, the result may be less obvious when upscaling a high-resolution image.
