What is the Roop Face Swap Extension? 

Roop is an extension for the AUTOMATIC1111 Stable Diffusion Web UI that enables users to perform high-quality face swaps on AI-generated images. It works by applying a selected face image onto the generated result after the initial rendering is complete. In short, Roop AI face swap lets you replace head faces seamlessly using Stable Diffusion.

It uses the inswapper_128.onnx model to detect and swap faces. You can get the Roop face swap GitHub extension to generate stylized, high-quality imagery using specific faces via Stable Diffusion, with no need for multiple images or manual alignment. With the help of Stable Diffusion’s advanced generative capabilities, Roop blends funny faces with striking realism, often producing results that are smooth, natural, and surprisingly expressive.

Pros:

• Seamless integration with Stable Diffusion workflows.
• Realistic, high-quality face blending.
• A few built-in video templates for quick creation.
• Supports facial customization via prompt and control.
• Can be used in batch workflows and img2img for more advanced editing.

Cons:

• Only supports video face swaps (no image support).
• Requires installation and setup within Stable Diffusion.
• Somewhat technical to get started.
• Limited templates compared to mainstream face swap apps.
• Multiple-face replacement requires manual input (e.g., entering face index numbers).

The Roop face swap extension is best suited for tech-savvy users, Stable Diffusion users, developers & extension creators, AI artists, or creators who enjoy tinkering with generative tools and want natural-looking results.

How to Run the Roop AI Face Swap Extension in Stable Diffusion?

Once you understand what Roop face swap extension can do, the next step is getting it up and running inside Stable Diffusion.

The Preparation for Roop Face Swapping in Stable Diffusion

Before you can face swap with Roop extension in Stable Diffusion, a few essential setup steps are required. Follow this preparation guide to ensure Roop is correctly installed and ready to use.

Step 1. On a Windows system, begin by installing Visual Studio (Community Edition). During the setup, make sure to enable the Python and C++ development workloads, as these are necessary for Roop’s dependencies.

Step 2. Open the Command Prompt, navigate to your Stable Diffusion Web UI directory, and run the command: pip install insightface==0.7.3.

Step 3. Launch Stable Diffusion, go to the "Extensions" tab, and under "Install from URL", paste the following repository link: https://github.com/s0md3v/sd-webui-roop. Click install, then close the Web UI once installation completes.

Step 4. Download the inswapper_128.onnx model file (this is required for face detection and replacement).

Step 5. Move the file into the following directory inside your Stable Diffusion setup:

/stable-diffusion/>/stable-diffusion-webui/>/models/>/roop/.

Step 6. After placing the model file, relaunch Stable Diffusion by running webui-user.bat. Roop should now be fully integrated and ready for face swapping.

After installation, it is simple and fast to face-swap videos with Roop. Note that Roop won’t work with NSFW images or photos where no face is detected. Make sure the face is clear and visible.

Step 1. In the Roop panel, import a photo with the face you want to apply.

Step 2. Make sure the “Enable” box is selected.

Step 3. (Optional) Restore faces. For better facial quality, choose CodeFormer under “Restore Faces”. Enter a positive prompt to guide the style and a negative prompt to avoid issues (like blur or distortion).

Useful Tips to Achieve Excellent Face-Swapping Results with Roop

• Use a clear, front-facing photo and avoid hats, hands, or filters.
• Always check "Restore Faces" below the sampling method to fix distortions.
• Adjust upscaler strength and sampling steps moderately to avoid over-processing.
• Try using an upscaler, or run img2img with low denoise (e.g., 0.1) and adjust as needed.
