I like the idea that I can go back and fill in the parts of a report that I couldn't finish in one sitting. This will a big help to me in my newly appointed position.

I mainly use it to edit papers for my teaching position; it's been very useful to not alter the original format while adding my view point freely on the document.

Just an amazing product and service. It has made managing and editing/updating PDFs a task i am no longer dreading to do. It has saved me SO MUCH TIME and headache working with PDFs.

This is by far the best I have tried; awesome features, well designed and intuitive as can be. Deeply regret I cannot afford to buy it; I run a very new, very poor legal aid society with 0.00 left in our budget for such things. Recommended highly.

The outputs of the system are great ... just your opening page is a bit confusing. I just wanted to look convert a document but couldn't see conversion icons - finally worked out that I have to use Add New button - remember people are coming to your website from other portals they have used before - and like me they look for a document conversion tool!
