Using Masks on Web

Masks let you select a specific part of your image to suggest a change. It’s a simple way to tell the AI: “Only change this area, and leave the rest as it is.”

How it works

  1. Click the Mask icon in the toolbar
  2. Draw a freehand shape around the area you want to modify
  3. While the mask is active, you can draw or erase inside that area
  4. When you’re ready, write a prompt to describe the change you want

Once you disable the mask, your brushwork will disappear.

Canvas influence will only affect the masked region.

Two ways to guide the AI with masks:

1. Draw inside the mask

Sketch directly within the masked area to suggest what you want to see.
Perfect for adding details or adjusting shapes without touching the rest of the image.

2. Erase + Draw

Erase part of the masked region to remove unwanted elements, then draw to guide the replacement.Great when you want to reshape or fully replace a section while staying in control.

Tip

Pro-Tip

Use the mask to sketch ideas or clean up shapes before prompting. Think of it as a temporary layer that helps direct the AI without modifying the original image.

Masks work best when the selected area isn’t too small. Very tiny masks may lead to less predictable results.
