Single-reference editing is the most common workflow: you provide one input image and describe the changes you want. FLUX.2 understands the context of your image and applies edits while preserving what you didn’t ask to change.
Refer to the Image Editing Overview for core concepts before diving into specific use cases.

​
Writing Effective Single-Reference Prompts

Be specific about what changes and explicit about what should stay the same. The more precise your instruction, the better the result.

Good prompts

  • “Change the shirt color to red”
  • “Replace the background with a sunset beach”
  • “Turn this into an oil painting”
  • “Add snow to the scene, keep everything else unchanged”

Avoid

  • “Make it better”
  • “Improve the lighting”
  • “Make it more professional”
  • “Fix the image”
