I use this software daily to mainly merge other documents into one PDF. It's very user friendly.
time management and expedition of documents requiring signatures!
Merge feature and being able to delete pages that I don't need. I like that I can save my agency's details on the different forms I use; rather than retyping each time.
It has locked up a couple of times but once I get out and go back in it's fine. It hasn't happened in the last year so they may have done some updates to the software.

Gets the job done!
Amazing, all sorts of adjustments can be made (Text, highlight, signature, templates etc). User friendly and a simple enough design. Cheaper too! My only issue is internet connection, perhaps if it was available offline (I'm not sure if that's a feature or not), it would honestly replace Adobe Acrobat all together.

I'm not sure why Adobe Acrobat Pro…
I'm not sure why Adobe Acrobat Pro isn't this easy to use. Adobe Acrobat Pro feels like it was created in a silo by people who don't do editing on a daily basis. Also, it doesn't install, on one of the latest Macbooks on the planet. Thank god for PDFEscape and PDFFiller. Thank you god.
