Hair Strategy

Choose how the app handles the hair during the swap. These are general guidance and the AI may take liberties.

  • Use source person’s hair – full face and hair from the source is transferred. The hair transfered may not align perfectly with the original.
  • Use target person’s hair – only the face is swapped, original hair remains

FAQ: FaceSwap App on the RunDiffusion Platform

What is the FaceSwap App on the RunDiffusion Platform?

FaceSwap is a cloud-based tool that lets you replace one person’s face with another directly in your browser. It’s designed for fast, high-quality, professional-grade swaps without installing software or configuring hardware.

Who is FaceSwap for?

It’s ideal for creators, designers, photographers, character artists, and anyone experimenting with AI-driven facial editing. It’s especially useful for quick concepting, photo corrections, and character development.

  1. Log in at app.rundiffusion.com/login
  2. Go to the RunDiffusion Platform
  3. Click Apps on the left sidebar
  4. Select FaceSwap from the app tiles

What images do I need for a face swap?

You need two images:

  1. Face to Swap Into Image: the source face you want to place into another image
  2. Image to Receive Swapped Face: the target image that will receive the new face

You can upload images, use your library, or select from recent generations.

Does image quality matter?

Yes. Higher-resolution images produce smoother alignment, better blending, and more accurate facial structure.

What does the Gender setting do?

You can choose Male, Female, or Non-Binary. This helps the model optimize structural alignment and improve realism during the swap.

What does the Hair Strategy option control?

You can choose:

  • Use source person’s hair: transfers the face and the source hair (may not align perfectly)
  • Use target person’s hair: keeps the original hair and swaps only the face

These are guidelines; the AI may interpret creatively depending on the image.

Can I upscale the final result?

Yes. Turn on the optional Upscale toggle to generate a higher-resolution output.

How do I generate my swapped image?

Click Run after selecting your inputs. Your result will appear in the session view, where you can inspect and download it.

Why did the hair or lighting change unexpectedly?

FaceSwap uses AI to reconstruct the blended face. In some cases, it may take creative liberties with hair, lighting, or fine details. If you need more granular control, you can use Facefusion in the RunDiffusion open-source applications.

Can I combine FaceSwap with other tools on RunDiffusion?

Yes. You can bring your results into Boards on the RunDiffusion Platform

Do I need a GPU or local installs?

No. Everything runs in the cloud on the RunDiffusion Platform. Just upload your images and generate.
