Swap a face or full head while preserving the scene

BFS Best Face Swap is a set of LoRAs for Qwen Image Edit and FLUX.2 Klein image editing workflows. In practical terms, it gives you a more focused way to transfer a face or full head from one image into another while trying to keep the target pose, lighting, body, and background.

The useful part is the workflow shape. You choose whether you want a face-only swap or a fuller head transfer, pick the matching BFS version, then feed the images in the correct order. Some versions use face first and body second. Newer head-swap versions invert that order, so the body image comes first and the face image comes second.

That makes the model easier to test than a generic prompt-only edit. You can start with two images, run the provided prompt pattern, and judge whether identity, lighting, skin tone, hair, and expression still look coherent in the final image.

Start with the public Flux2 Klein Face Swap demo if you want the fastest browser test. Use two consent-cleared images: one target scene or body image, and one reference face. Run a simple first test before trying harder cases, such as swapping a face into a portrait with similar angle and lighting.

For a local run, use the BFS model page and the bundled ComfyUI workflow JSON files. Pick the workflow that matches your base model and BFS version, then follow the README's image order carefully. A good first local test is to compare face-only swap against head swap on the same pair of images so you can see which one preserves the target scene better.

This is a face-swap workflow, so the editorial frame needs to be clear. Use consent-cleared images, avoid public figures, and treat identity drift or non-consensual use as hard limits. Local testing also needs the matching Qwen Image Edit or FLUX.2 Klein setup, so this is not a one-click local tool.

• Test consent-based face replacement for creative image edits.
• Compare face-only swaps with full head swaps on the same source pair.
• Preserve a target pose, outfit, or background while changing identity.
• Build a ComfyUI workflow for controlled character or campaign mockups.
• Stress-test whether lighting and expression stay believable after the swap.
