Transform your existing images into stunning visuals with FLUX.1 [dev] Image-to-Image, a high-performance endpoint that enables rapid transformation of existing images, delivering high-quality style transfers and image modifications with the core FLUX capabilities.
Overview
FLUX.1 Image-to-Image is built on the powerful 12-billion parameter FLUX.1 [dev] flow transformer, designed specifically for transforming existing images based on text prompts. The model excels at style transfers, image modifications, and artistic variations while preserving the core composition of the input image.
Key Capabilities
Image-to-Image Transformation
- Transform existing images using natural language descriptions
- High-quality style transfers and artistic modifications
- Preserve core composition while applying creative changes
- Support for various image formats: jpg, jpeg, png, webp, gif, avif
Performance Optimizations
- Rapid transformation with optimized inference pipeline
- Production-ready API with enterprise scalability
- Suitable for both personal and commercial use
- Consistent, high-quality results across multiple generations
Getting Started
Setting up FLUX.1 Image-to-Image is straightforward. First, install your preferred client library:
For JavaScript/TypeScript:
npm install --save @fal-ai/client
For Python:
pip install fal-client
Initialize the client with your API key:
import { fal } from '@fal-ai/client'
fal.config({
credentials: 'YOUR_API_KEY'
})
Making Your First API Call
Transform your first image with this example:
const result = await fal.subscribe('fal-ai/flux/dev/image-to-image', {
input: {
image_url: 'https://your-image-url.com/image.jpg',
prompt: 'Transform this into a watercolor painting style',
strength: 0.8
}
})
Best Practices
Maximize the quality of your image transformations:
Write Clear, Descriptive Prompts
Consider including specific details about the desired style, artistic direction, or modifications. For example, instead of "make it artistic", try "transform into a vibrant oil painting with visible brush strokes and rich colors".
Optimize Transformation Parameters
- Use strength parameter to control how much the image changes (0.1 = minimal change, 1.0 = maximum transformation)
- Start with moderate strength values around 0.7-0.8 for most use cases
- Use consistent seeds when you need reproducible results
Handle Input Images
- Ensure input images are high quality for best results
- Supported formats: jpg, jpeg, png, webp, gif, avif
- Use drag-and-drop functionality or provide base64 encoded data URLs
