Best Use Cases

Character Modification — Change attributes like gender, age, clothing, or appearance.

Object Replacement — Swap elements within images while preserving context.

Style Transfer — Apply different visual styles to existing images.

Text Editing — Modify on-image text while maintaining design consistency.

Scene Adjustment — Change backgrounds, lighting, or environmental elements.

Pro Tips

Use clear, specific edit instructions for best results (e.g., "Change the man to a woman" rather than "modify the person").

Start with fewer reference images (1–3) for simpler edits.

More reference images can help with complex compositions but may affect stability.

2K offers the best value — same price as 1K with higher resolution.
