What is Stable Diffusion and its ReActor Extension?

Before we take a deep dive and explore a stepwise guide on how to face swap in Stable Diffusion, let’s cover some basics.

Difusão Estável

If you are into graphic designing or editing, then you must have heard of Stable Diffusion. Developed by Stability AI, it is a generative AI model that creates realistic images by gradually refining a random noise input.

It works by repeatedly applying small changes to the initial noise, adjusting it to match the characteristics of a target image. This process, called diffusion, ensures stable and coherent image generation and is used to create high-quality, realistic images with customized details.

ReActor Extension

Now, ReActor is one of the most popular web extensions that enhances and customizes the Stable Diffusion AI model. In a nutshell, it enables users to dynamically modify the generated images in real-time, influencing various aspects like colors, textures, and shapes. That’s why the model can be used to create more personalized outputs by leveraging the power of Stable Diffusion.

Mostly, the ReActor face swap feature has gained popularity as it is freely available and yields exceptional results.

How to Face Swap in Stable Diffusion using the ReActor Extension?

Since Stable Diffusion is an open-source model, using it is free, but it can be a bit complicated. To learn how to face swap in Stable Diffusion using the ReActor extension, you have to follow these steps:

Step 1: Install and set up the ReActor extension

First, you have to install this Stable Diffusion face swap extension on any popular web UI, like Automatic1111 or ComfyUI. In this post, I have considered the example of Automatic1111 as it is the most popular Stable Diffusion web UI.

You can go to your Automatic111 interface and visit Extensions > Install from URL section. Here, you need to enter the GitHub URL of the ReActor extension, which is: https://github.com/Gourieff/sd-webui-reactor

Simply wait for a while as Automatic111 loads the necessary components of the ReActor extension to your account. Once that is done, you can go to the txt2img tab on your Automatic111 interface and enable the “ReActor” extension to work.

Step 2: Upload the images you want to face swap

After the ReActor extension is enabled, you can simply access it on your Automatic111 interface. Now, to use the ReActor face swap feature, you can go to its “Main” section and upload your images. First, you have to upload the image from which the face cutout has to be done (on the left).

Now, click on the add icon and upload the target image. That is, the image on which the cut-out face would be pasted.

Step 3: Swap faces using the ReActor extension

Once you have uploaded the images, scroll a little and make sure the “Face Mask Correction” feature is enabled, which will automatically correct any glitches in the output image. Also, go to the “Restore Face” section and select the “CodeFormer” option from here.

Lastly, you just have to enable the “Swap in Source Image” option to let the app know that the source image has to be swapped. Once that is done, you need to scroll a little and set the denoising strength to a low value (I would recommend somewhere around 0.125-0.25) to get the desired results.

Now, you can simply customize other parameters like the image size, number of steps, CFG scale, etc. as per your choice. I recommend playing around with these settings to get customized results. Lastly, just click on the “Generate” button and simply wait for a while as the Stable Diffusion face swap tool produces the desired output.

You can review the results and download the generated image on your system. If you are not satisfied, then you can simply change the denoise level, number of steps, sample style, and so on.
