Features

FLUX SRPO — Image-to-Image

FLUX SRPO Image-to-Image is a powerful image transformation model that converts existing images into new styles based on text prompts. Upload an image, describe the transformation you want, and the model generates a stylized version while preserving the original composition.


Why It Stands Out

  • Image-to-image transformation: Convert images into new styles while preserving structure.
  • Prompt-guided generation: Describe the visual style you want to achieve.
  • Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
  • Adjustable strength: Control how much the output differs from the original.
  • Multiple output formats: Export as JPEG or PNG based on your needs.
  • Fine-tuned control: Adjust guidance scale and inference steps for precise results.
  • Reproducibility: Use the seed parameter to recreate exact results.

Parameters

ParameterRequiredDescription
promptYesText description of the desired visual style.
imageNoSource image to transform (upload or public URL).
strengthNoTransformation intensity (0.0–1.0, default: 0.8).
num_inference_stepsNoQuality/speed trade-off (default: 28).
seedNoSet for reproducibility; -1 for random.
guidance_scaleNoPrompt adherence strength (default: 3.5).
output_formatNoOutput format: jpeg or png (default: jpeg).
enable_base64_outputNoReturn base64 string instead of URL (API only).
enable_sync_modeNoWait for result before returning response (API only).

How to Use

  1. Upload your source image — drag and drop a file or paste a public URL.
  2. Write a prompt describing the visual style you want. Use the Prompt Enhancer for AI-assisted optimization.
  3. Adjust strength — lower values preserve more of the original, higher values allow more transformation.
  4. Adjust parameters (optional) — fine-tune guidance scale and inference steps.
  5. Click Run and download your transformed image.

Best Use Cases

  • Style Transfer — Convert photos into paintings, illustrations, or artistic styles.
  • Visual Effects — Apply consistent visual treatments across multiple images.
  • Content Repurposing — Transform images into different aesthetic styles.
  • Design Exploration — Explore different visual directions from existing images.
  • Creative Projects — Experiment with unique visual transformations.

Pro Tips for Best Quality

  • Use lower strength (0.3–0.5) to preserve more of the original image structure.
  • Use higher strength (0.7–0.9) for more dramatic style transformations.
  • Be specific in your prompt about the style, mood, and visual treatment.
  • Use PNG format when you need higher quality or transparency support.
  • Fix the seed when iterating to compare different strength or prompt variations.

Notes

  • Ensure uploaded image URLs are publicly accessible.
  • Processing time varies based on current queue load.
  • Please ensure your content complies with usage guidelines.

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation.
imagestringNo-The image to generate an image from.
strengthnumberNo0.80.00 ~ 1.00Strength indicates extent to transform the reference image.
num_inference_stepsintegerNo281 ~ 50The number of inference steps to perform.
seedintegerNo-1-1 ~ 2147483647The random seed to use for the generation. -1 means a random seed will be used.
guidance_scalenumberNo3.51.0 ~ 20.0The guidance scale to use for the generation.
output_formatstringNojpegjpeg, pngThe format of the output image.
enable_base64_outputbooleanNofalse-If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
enable_sync_modebooleanNofalse-If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
