Upscale Images with FLUX AI in ComfyUI

Education

Introduction

In this article, we will explore the process of upscaling images using FLUX AI within the ComfyUI framework. Upscaling is a technique to enhance the resolution and clarity of images, making them appear smoother and more detailed.

Visual Comparisons

Let's start with a visual comparison. On the left side, we have an image generated by FLUX, and on the right is its upscaled version. You will notice a significant difference: the upscaled image presents a much smoother and clearer appearance.

Example Comparison

Here is another example to consider. Again, the left image was generated by FLUX, while the right image showcases the upscaled version. In this case, the face in the image appears smoother and significantly clearer after the upscaling process.

Text Upscaling

One more notable example demonstrates how the text within the image is improved during upscaling. The clarity and readability of the text noticeably enhance, providing a better visual experience.

The Workflow

Now, let's take a look at the workflow involved in upscaling images. Initially, we generate images using FLUX. After that, we proceed to the upscaling phase.

  1. Image Generation: We begin with the image generation workflow using FLUX.

  2. Upscaling: For the upscaling process, we utilize the Ultimate SD Upscale Node. The Real ESRGAN model is employed for better results.

  3. Tiling: The original image is divided into four parts (tiled) and then sent through the upscaler.

  4. Integration: The SD upscaler combines the capabilities of FLUX and ESRGAN to perform the upscaling process seamlessly.

Feel free to experiment with this process and enjoy the enhanced images!
