# Erase tool

The **Erase** Tool allows you to remove unwanted objects, blemishes, or distractions from your photo using AI-powered content-aware fill.

* **Brush Size** – Adjust the brush diameter by sliding left (smaller) or right (larger).
* **Undo/Redo** – Use the back arrow to undo a stroke or the forward arrow to redo it.
* **Checkmark** – Apply changes.
* **X Icon** – Cancel without saving.

Pro Tip: After erasing, zoom in to check edges. Use the Undo button to refine your results with precision.
{% endhint %}

**How to Use:** Tap the Erase icon. Resize the brush, then drag your finger across the object you want to erase. The selected area will be highlighted. Luminar uses nearby pixels to fill in the erased area with natural-looking texture. Tap the checkmark to apply or use Undo to refine.

**When to Use**: Ideal for removing small distractions (power lines, skin blemishes, dust spots), or even large objects like people or cars in the background.
