If you are struggling with sensitive PDF documents that you want to lock with a password, I advise a lightweight application known as Softaken PDF Locker. With this offline utility, you can easily lock any lightweight or heavy PDF document. Also, it allows unauthorized permissions like printing, editing, and copying. It works without Adobe Acrobat, and it is very easy to use. The advanced utility preserves accurate results without damage or losing format. This application smoothly works on all Windows versions, ensuring you can lock your PDF without technical issues.
