🖼️ Free AI Image Upscaling Tool Introduction

The script introduces a free AI tool for image upscaling and sharpening. It can be run offline on a computer without the need for an internet connection. The tool, named 'upscale,' is available in both desktop and cloud versions. The cloud version is not yet available but offers additional features like face enhancement. The video demonstrates the installation and usage of the desktop version on a Windows laptop without a dedicated Nvidia Cuda GPU. The process involves uploading an image, selecting an upscale algorithm, choosing an output folder, and initiating the upscaling process. The tool is capable of batch upscaling and is shown to produce impressive results, even at a 1x scale, by reducing noise and sharpening details.


📸 Testing AI Image Upscaling with Various Algorithms

This paragraph details the testing of the AI upscaling tool using different algorithms on various images. The original images are described as small and blurry, with a specific focus on an icon, a dog photo, and a portrait. The tool's settings allow for upscaling by a default of 4X, but the video also explores the effects of setting the scale to 1X, demonstrating that it can still improve image quality by reducing noise and sharpening details. The video compares the results of different algorithms, such as 'Ultra sharp' and 'Real ESR,' noting subtle differences and the impact on image realism. The final test is on a dog photo, which shows significant improvement in detail and sharpness after upscaling. The script also mentions a sponsored tool, upix, for generating realistic images and ends with a demonstration of the batch upscaling feature, which saves the results in a separate folder.



💡AI Tool

An AI Tool refers to software or applications that utilize artificial intelligence to perform tasks, such as image processing. In the context of the video, the AI Tool is used for upscaling, unblurring, sharpening, and adding details to images. It is presented as a free and efficient solution that can be run on a computer without an internet connection, showcasing its capabilities through the upscaling of various test images.


Upscale, in the context of image processing, means to increase the resolution of an image while maintaining or enhancing its quality. The video script describes the process of using the AI Tool to upscale images, such as transforming a small, blurry image into a larger, clearer one, as demonstrated with the test images like the icon and the dog photo.


Unblur is the process of making a blurred or unclear image appear sharper. The video script mentions the AI Tool's ability to unblur images, which is evident when the presenter shows the before and after results of the upscaling process, especially with the dog photo where the details become much clearer.


Sharpen is a term used to describe the process of enhancing the contrast along the edges within an image to make it appear more defined. The video demonstrates the sharpening effect of the AI Tool when the presenter compares the original blurry images with the upscaled versions, which have more detailed and crisp edges.

💡Add Details

Adding details to an image refers to the process of enhancing or creating additional visual information within an image that was not clearly visible before. The video script illustrates this with the example of the portrait of a person, where the AI Tool adds more detail to the skin texture and facial features after upscaling.

💡Cloud Version

A cloud version of a software application refers to a service that runs on remote servers and is accessed over the internet. The video mentions a cloud version of the AI Tool that offers additional features like face enhancement, but it is not yet available, requiring users to join a waitlist.

💡Desktop Version

The desktop version is a type of software that is installed and run on a local computer. The video focuses on the desktop version of the AI Tool, which can be used offline and does not require specialized hardware like an Nvidia Cuda GPU for operation.

💡Batch Upscale

Batch Upscale is a feature that allows the user to process multiple images at once, rather than one by one. In the video, the presenter demonstrates this feature by selecting a folder of images and upscaling them all in one go, saving time and effort.


In the context of the video, an algorithm refers to the different methods or processes the AI Tool uses to upscale images. The script mentions several algorithms, such as 'Ultra Sharp' and 'Real ESR', each offering subtle differences in the results, and the presenter suggests trying each one to see which works best for a particular image.

💡Upscale Algorithm

An upscale algorithm is a specific set of instructions or rules used by the AI Tool to increase the size of an image. The video script describes choosing different upscale algorithms to see which one yields the best results for the test images, indicating that the choice of algorithm can affect the quality of the upscaled image.
