How to edit part of a photo with AI

Choose an area and describe the change you want in AI Fill.

1. Open a photo

Start with a photo you want to edit. Keep the original so you can compare the result later.

2. Select the area

Use the app’s Freehand or Lasso selection tools to mark the area you want to change. Check the mask before generating an edit.

3. Describe the change

Enter a specific text prompt. For example: “Replace the cup with a blue ceramic mug.” This is an example instruction, not a promise of an identical result.

4. Generate and review

Review the AI-assisted result, including the area around your selection. If the edit misses your intent, refine the selection or prompt and try again.

Keep your edit focused

A smaller, deliberate selection and a clear description can make an edit easier to judge. AI output can change details, so review the full image before saving or sharing.
