Yes, you can absolutely customize the target design for your own personal use! That's exactly why we give you the original PNG images along with the target PDF files. However, we do ask that if you decide to personalize and customize the target designs, that you do not resell or redistribute the target designs to others. 

The PNG images are provided so that you can create PDF files of specific sizes (like the 24x36 inch PDF files we include with every standard target). 

If you have other questions about how you can use or customize the target designs, please reach out to our support team.
