I have been working as a professional software developer and freelance consultant for over 10 years. Keeping documents in a platform independent and secure format is critical to me and to my consultancy clients. This pdf software is amazing, through its password protection, allows me to keep my documents secure. The ability to embed source code into password protected PDF documents is quite handy. Once finished from a project, I simply embed the files into the Project Manual, password protect it, and send them to my client.
This is the only one feature I have told you, which helped me the most, there are many others too. All types of conversion are possible just in few minutes mostly depending upon the size, but still very less as compared to the other products. I mostly use it for word to pdf conversion, and the result is brilliant, everything in the same format, just like a carbon copy without the miss of even a single dot. I have also used it for pdf print and for extracting few pages out of the whole document.
