If you need to delete a layer, you have the option to delete the content and markups within the layer or move this information to the base PDF.
Go to View -> Tabs –> Layers or press ALT+Y to show the Layers tab.
Select the layer and click Delete Layer. The Delete Layer dialog box will appear.
You can also right-click the layer and select Delete.
To delete multiple layers at the same time, hold down SHIFT or CTRL and select the layers.
The layers that will be deleted are listed at the top of the dialog box after Delete Layer. If this list contains a layer you do not want to delete, you’ll need to click Cancel and start over.
To delete the content on these layers, select Delete Layer Content on Page. Otherwise, the content will be moved to the base PDF.
To delete the markups on these layers, select Delete Layer Annotations. Otherwise, the markups will be moved to the base PDF.
Note: Unchecking both boxes deletes the definition of the layer and keeps all content and markups by moving them to the base PDF.
