MaskIt is an Adobe Acrobat plug-in that lets users mask specific areas (inside or outside a defined area) in PDF documents, blocking anything that would ordinarily display or print in them.

It is worth noting that MaskIt can create masks that remove information from either inside or outside a particular area, allowing users to remove logos, dirty areas resulting from scanning, confidential information or headers and footers, amongst other things. The configurations can be saved and reused from the Mapsoft MaskIt option accessed from Acrobat's Plug-ins menu.
MaskIt also features an array of functionalities that make the process of masking easy and hassle-free. Users can mask areas internally or externally to a defined area, mask odd and even pages, define distribution to page ranges, and easily define masks using the [mask] tool. Also, MaskIt allows for the masking of multiple pages simultaneously.
Another benefit of using MaskIt is that additional items can be added to the masked areas later using a PDF stamping tool. It is essential to note that additional items that might be added to the PDF later, such as the text output from Impress and Impress Pro (both sold separately), are also displayed.
In summary, MaskIt is an efficient desktop publishing tool aimed at making it easy for users to remove information from PDF documents. It offers an array of functionalities that make the masking experience seamless, and its configurations can be saved for future use. Hence, if you're looking to mask content on your PDF, MaskIt is an excellent tool to have in your arsenal.
