What it is good for
Professional inpainting with FLUX.1 Fill Pro
Pro-tier inpainting and outpainting with mask support — seamlessly extend scenes or replace masked regions with prompt-guided generation.
Canvas extension
Outpaint backgrounds for new aspect ratios or banner crops.
Retouching workflows
Fix small regions in product or portrait images without full regenerations.
Key capabilities
Why creators pick FLUX.1 Fill Pro
Mask-based editing
Paint what should change; Fill regenerates masked areas to match the scene.
Outpainting support
Extend canvases beyond the original borders with coherent context.
Pro-quality blending
Edges and lighting blend more convincingly for delivery work.
Prompt-guided fills
Describe what belongs inside the mask instead of cloning nearby pixels.
Tunable steps
Adjust inference when fills need tighter adherence or smoother blends.
How to get a strong result
Tips for better results
Start with the subject, then add lighting, style, and anything that must stay the same. Upload a reference whenever you want a more controlled edit.
- 1
Feather masks slightly
Soft mask edges help Fill blend into surrounding pixels.
- 2
Describe context in the prompt
Mention lighting, material, and perspective for masked regions.
- 3
Try Dev for mask tests
Validate mask shapes on Fill Dev before Pro delivery.
- 4
Outpaint in stages
Large extensions work better as several smaller outpaint passes.
