Donation

Is PDFedit free? Yes, it is. You must only comply with the terms of the GNU General Public License. However, the fact that you can get the software for free doesn't mean that there is no cost to the people involved in producing it for you. The people who bring you PDFedit have often invested a considerable amount of their personal time into making PDFedit the best and providing you with any support you need. This is particularly true for PDFedit developers. Thank you for you donation.
