# Fill Opacity

The Fill opacity allows you to set how transparent a fill color is. This is different to [Layer opacity ](/editor/properties/visibility.md#opacity)as it only applies to the specified fill of the layer and not its other properties such as stroke or other '[stacked fills](broken://pages/TBd3dlqqhbO22GoQj2OT)'

To change the Fill opacity:

* Select your layer and go to the property panel
* In the Fill property section, you can change the opacity between the values of 0% and 100%.
