Pros & Cons from Real Users Pros Free, well-featured pdf editor. Contains more features, like signing, editing, moving pages, that other basic pdf viewers don't have. A good freemium software for reading PDFs. There are very few complaints on this front. Have been using it consistently for many years. It's amazing with editing and sharing of PDF files. Great with integration with other apps. There is a free version to install. Easy to use when you need to open up a PDF file on a computer to view information. Very user friendly. Easy to create, edit, sign and send PDF documents. Some situations call for secured PDFs so they can't be edited and that is very helpful too! Cons This program can get slow and bulky at times. As part of Adobe, there's always the ad push to get you to sign up for more. Sometimes it acts buggy and fails to load element such as signatures. Great product which works effectively with PDF document. There isn't anything that I dislike about it to be honest. Monthly subscription, my boss is trying to get me to downgrade to Adobe 2007 but I don't want to loose all the features.
