Use a mask to fill or replace selected areas (e.g. new background, object, or outfit) while keeping the rest of the image intact. Great for localized, non-destructive edits.
The best image results come from specific composition, style, and lighting language. Be explicit about what should be in frame and what should feel dominant.
Best results start with a precise subject, composition, and style direction.

| Option | Values | Notes |
|---|---|---|
| Image | Your upload | Base image |
| Mask | Your mask (region to fill) or edges | Defines area to fill or extend |
| Prompt | Your text | What to generate in the filled region |
| Strength | Low–High (check Pixio) | How much to change the region |
| Credits | Plan-based | Check model card in Pixio |
Credits are plan-based; check the model card in Pixio for your plan and cost per image.
[What to put in the filled region]. Describe only the content for the fill (e.g. "blue sky with clouds", "same person smiling", "continue the forest"). Match lighting and style to the rest of the image for a seamless result.
"Blue sky with soft clouds. Match the lighting of the scene."
"Same person, smiling. Natural expression. Match skin tone and lighting."
"Continue the landscape to the right. Same style and lighting. Seamless."
"Bookshelf with books. Same interior style. Seamless blend."

Tell the model what should dominate the frame first.
Use lighting language early; it changes everything downstream.
When editing, describe what stays, not just what changes.
References help when continuity matters more than novelty.
A strong image prompt defines the subject, composition, lighting, and finish instead of leaving them implied.
Use precise visual language to control subject, composition, lighting, and style from the start.
Preserve the useful parts of the image while steering the rest with masks, references, or prompt edits.
Bring in reference images or LoRAs when consistency is more important than exploration.
Flux Pro Fill is strongest when the visual brief is specific about framing, style, and what should read first.
Use it for campaign images, product shots, subject consistency, or polished concept work.
When editing, say exactly what changes and what must remain untouched.
Lock the subject, composition, and lighting direction before you chase style nuance.
Use references or edits when the same subject, style, or layout has to survive across versions.
Once the frame works, refine only the weak areas instead of rewriting the whole composition.
Finish strong compositions by scaling them without rebuilding the frame from scratch.
Use editing tools after the initial generation when the composition is right but the details still need polish.
