You try to zoom into an image or enlarge it for a print, but it becomes blurry, jagged, or pixelated. This is one of the most common problems faced by all with low-resolution images. Whether it’s an old photo or a small size low resolution photo, enlarging leads to a loss of quality. 

But what if you could turn out the same image into a high-resolution one just by upscaling it? Let’s understand what image upscaling is and how it works with traditional and AI techniques. While traditional upscaling stretches the pixels by interpolating them, AI-powered techniques reconstruct details by preserving quality.

In this blog, I’ll walk you through the insights of how to upscale an image effectively, what tools you can use, and what best practices you should follow. 

What is image upscaling?

Image upscaling is the method of increasing the dimensions and adding new pixels to an image. When you try to enlarge an image by stretching it beyond its original resolution, it becomes pixelated. It’s important to know the difference between resizing and upscaling. Resizing simply changes the image dimensions and often leads to a loss in quality, especially while increasing size. 

Traditional image upscaling vs AI image upscaling 

Traditional image upscalers like Photoshop and other software use interpolation methods such as:

• Nearest Neighbor: Fast, but the image ends up with jagged edges.
• Bilinear: Makes things look smoother, but you lose some sharpness and detail.
• Bicubic: A step up from bilinear—images look nicer, but if you zoom in 4x or 8x, it still gets a bit blurry.

These traditional methods come with several disadvantages, such as blurry edges and jagged lines. These days, Photoshop has stepped up its game with AI plugins like Super Zoom, Preserve Details 2.0, and Neural Filters that use deep learning to upscale images.

On the other hand, AI image upscaling works on learned patterns and adds pixels to the missing details in the image.

Benefits of image upscaling include; 

• Preserving textures and fine details.
• Enhancing the facial and background elements.
• Reducing noise and grain from old or compressed images.

How do I upscale an image with AI tools?

Traditionally, if you wanted to upscale an image, you had to rely on tools like Photoshop, GIMP, or other softwares. Image uspscaling using traditional methods results in to blurry, stretched, or full of jagged pixels.

But with AI-powered upscalers, image upscaling has totally changed. These tools are smarter than the traditional ones, they use deep learning to understand what your image should look like, picking up on patterns, textures, and edges to fill in the missing pieces naturally. Here are some of the best-performing AI image upscaling tools I have tested below:
