Works for everything Overall I am a fan of the software. I know not everything is supposed to work 100% of the time and things will happen so that doesn't deter me from using the software or recommending it someone else. I liked the ability to install and go, this software worked for getting documents in, filling them out, and getting them back out. I like the options and the ability to even save some data. Sometimes it has crashed or felt a little clunky. I am unsure if it is saving the data but during the saving process it has crashed on me and that is something i wasn't as much a fan of.

Locking a PDF can protect the integrity of a document. If you have made comments on a document, or approved a specific version of a document before exporting it as a PDF, locking the PDF from editing can prevent anyone from making changes afterwards.
