AI Face Swap Online: Photos and Video in Your Browser

Most face swap tools hide the machinery behind one button and a marketing word. Wireflow shows you the parts. A face swap here is a small workflow you own on a node canvas: two Import nodes hold the source face and the target photo, a Text Input carries the instruction, and a single Face Swap node does the work. Nothing to install, nothing running on your machine; it all runs on hosted compute in the browser.

The Face Swap node runs Nano Banana Pro, a multi-reference image editor. It reads both of your images at the same time and rewrites the target so the source identity sits on the existing pose, hair, and lighting. There is no separate deepfake engine and no black box: it is the same kind of edit you would use to restyle a product shot, pointed at a face. The same canvas drives the rest of your AI image editor work, from headshots to batch runs.

The workflow behind this page's button is small on purpose: three input nodes, one edit node, one sticky note.

• Source Face and Target Photo are Import nodes. Upload the face you want to transfer and the photo you want to change; both accept a normal image file.
• Swap Instruction is a Text Input. It tells the editor to place the first face onto the second person while keeping pose, hair, clothing, and background, so the blend behaves the way you want.
• Face Swap runs Nano Banana Pro. Both images and the instruction wire into the one edit node, which reads all three at once and returns the swapped photo in a single pass.

Because the swap is one node, the model is a slot you can change: drop in Nano Banana 2 or Flux Pro Kontext Max and the wires stay put. And because the graph lives among dozens of hosted model nodes, the swapped still can roll straight into an AI avatar generator or an image-to-video node without leaving the browser.

This flow swaps a face in a still image. It does not do automatic frame-by-frame face replacement on a video you already filmed; there is no video face-swap node in the registry. The honest video path is to swap the face in a photo, then animate that swapped still with an image-to-video node, which is a different thing from tracking and replacing a face across existing footage.

A few other limits worth stating plainly: results depend on clear, well-lit source and target images, and a hard angle or a covered face will fight the blend. You need both images, so this is not a one-click swap of a stranger from a single photo, and you are responsible for having the right to use the faces you upload. What Wireflow gives you instead is an editable pipeline, a swappable model slot, and per generation pricing, so building the AI headshot generator style graph is free and you only pay when a node runs.
