There is no doubt that people would not want to view pixelated pictures. This typically happens when someone tries to enlarge an image but compromises its quality as a whole. As a result, the image usually looks blurry and not visually appealing. So it is important that if you upscale an image, quality must also be taken into consideration.

Image Upscaler is software that increases the resolution and size of an image. This process is also known as “image super-resolution.” Image upscale work by analyzing the existing pixels in the image and adding new pixels to increase the overall size.

Brief History and Basics of Image Upscaling

The concept of image upscale has been around since the early days of digital imaging. One of the earliest methods, nearest-neighbor interpolation, dates back to the 1970s. As technology improved, more sophisticated methods for upscaling images were developed, such as bilinear and bicubic interpolation in the 1980s and 1990s.

With the advent of deep learning, recent years have seen a surge in research and development of deep learning-based methods for image upscale, which can produce high-quality results. The field is constantly evolving, with new methods and techniques being developed to further improve the quality and speed of image upscale.

At the same time, it also does its job to preserve the original image’s quality and details. The results can vary depending on the method and quality of the upscaler, but the overall goal is to produce a larger image that appears to be of higher quality and resolution.

The basics of an image upscale include:

  • Input image: The original image that will be upscaled.
  • Upscaling algorithm: The mathematical or artificial intelligence-based method used to increase the resolution of the image.
  • Output image: The resulting upscaled image, with increased resolution or size.
  • Interpolation: A process used to estimate missing pixel values based on surrounding pixels. This is a crucial step in upscaling images as it helps to create new pixels that fill in the gaps between existing pixels.
  • Quality control: Evaluating the quality of the upscaled image to ensure that it meets desired standards for resolution, detail, and clarity.

The specific steps and processes used in an image upscaler can vary depending on the method, but these are the basic components that are involved in the upscaling process.

Why Upscale?

There are several reasons why someone might choose to upscale an image:

  • Improved resolution: For a more detailed look specifically for images that are in extremely HD, upscaling could really be an asset mostly if used for business purposes mostly for advertising efforts.
  • Larger size: Some images are really small but still you would want to use them for whatever purpose you like resizing them in a larger form could affect quality. Upscaling is taking away this dilemma, especially for non-technical users.
  • Compatibility with new technologies: The latest technology would need higher-resolution images. You will not be able to upload them to their platform if the image is not able to reach the required minimum resolution requirements.
  • Restoration: Well, there are photos that we would want to make look significantly better by making them clearer and detailed, this is where upscaling comes in. 
  • Creative purposes: A surreal effect might be achieved if upscaling is used on photos that are already clear and detailed.

Ultimately, the decision to upscale an image depends on the specific needs and goals of the person or organization. There are various ways that you can do to upscale an image, you just choose depending on your expertise. Here are some examples:



Algorithms such as bilinear, bicubic, and Lanczos interpolation can be used to add pixels to an image and make it larger.

Neural networks

Models such as super-resolution Generative Adversarial Networks (SRGANs) can be trained to upscale images.

Enlargement software 

Many commercially available software programs can be used to enlarge images, such as Photoshop and GIMP.

Image Upscaler

AI software that uses deep learning algorithms to upscale images.

What’s Next?

Moreover, there are lots of online apps today that offer image upscaling but only a few upholds what the software must do which is to increase size without compromising quality. 

Nevertheless, the same algorithms are used to create those pieces of software but Graphical Users Interfaces (GUIs) are enhanced to make them more user-friendly to people without technical skills in editing.

A great example of a reliable image upscaler is the Image Upscaler. It is a very efficient online app that can do wonders on any image. It can resize and improve image quality in no time. You’ll surely never waste time anymore finding the right image upscaler for your needs. Plus, you will not need to hire a professional to do the job which will save you money in the long run.
