Input

Prompt(string)

Natural-language styling instructions describing how the garment should be worn on the person (e.g. tucked in, layered, sleeves rolled up).

Inference Steps(integer)

The number of denoising steps to perform. Range: 1 to 4.

Output Format(string)

The format of the generated image. Allowed values: jpeg, png.

Seed(integer)

The same seed and the same input will output the same image every time. If not provided, a random seed is used.

Garment Image URL(string)

Upload

PNG, JPEG, WebP, or GIF · 20 MiB maximum

The URL of the garment reference image. Maximum 1 megapixel; recommended around 0.5 MP. Multiple garments must be merged into a single composite image before submission.

Human Image URL(string)

The URL of the person image that the garment will be applied onto. The output keeps this image's aspect ratio. Maximum 2 megapixels; recommended under 1 MP.

API README

FLUX Virtual Try-On

FLUX Virtual Try-On is a image generation and editing workflow in the FLUX family. Flux Pro 1.0 Vto by BFL - AI-powered image editing, style transfer, and transformation. Edit photos with natural language instructions, remove backgrounds, change styles, and enhance images effortlessly. It is designed to translate deliberate creative direction and supplied reference material into a coherent production asset, with attention to subject identity, composition, visual detail, and the specific transformation implied by this exact route.

Use this route when the project needs a virtual garment visualization. Describe the intended result, what must remain recognizable, and the required composition, lighting, materials, atmosphere, and finish; keep technical delivery choices in the schema fields below.

Highlights

Virtual garment try-on. Combines a person image and clothing reference to visualize the garment on the subject.
Identity preservation. Keeps the wearer recognizable while changing apparel.
Garment-detail transfer. Carries color, cut, texture, and visible design cues from the product reference into the result.
Photorealistic integration. Adapts drape, lighting, perspective, and body placement so the clothing belongs in the scene.

When to Use

✅ Good fit	❌ Consider alternatives
The project needs this exact FLUX capability	The intended task belongs to a different media workflow
Required source and control media are available	Necessary assets or usage rights are unavailable
Creative direction can state change and preservation goals	Output must be deterministic at pixel or frame level
Supported dimensions and formats match final delivery	Placement requires unsupported specifications
An asynchronous generated result fits production	A live frame-synchronous response is mandatory

Prompt Guide

Lead with the main subject and action, then specify composition, context, lighting, materials, style, typography, and atmosphere. For editing, identify each source and clearly separate the requested transformation from the subjects, regions, geometry, or identity that must remain unchanged.

{
  "prompt": "A cinematic, precisely composed result with a clear subject, controlled camera or viewpoint, realistic lighting, exact materials, and intentional atmosphere",
  "seed": 1,
  "output_format": "jpeg",
  "human_image_url": "https://example.com/reference.png"
}
