It works well and fulfilled all my needs for many years., but when I needed to transfer the licence from one laptop to another things fell apart.

Paralegal

I really enjoy the comprehensive features that assist with work efficiency and integration with Microsoft programs.

Quality Intervention Specialist

Honestly the bulk file conversion feature cannot be stated how great that is being able to turn 50 word docs into 50 PDFs is magical.

Incorrect information from support, quick to take money for a licence impossible to get it back when they fail to provide the software.

Senior Program Manager

It offers multiple ways to convert your document and even allows you to sign it.

I love the digital signature and document modification features the most.

Executive Assistant

Only thing that is annoying is that it tends to default to the app for all PDFs which is not necessary - not really due to Nitro!

Product Owner

Lacks the advanced features of Adobe Acrobat Pro.

I’d like the “printer ID” to be much more visible (to avoid clicking on Adobe PDF)

Director of IT

It is not always a 100% match for what Adobe can do depending on what features you need, so there are some times when we need to reach outside of the product to find a solution.

It can't open some pdf files (says they're corrupted - but they're not since Adobe Acrobat Reader can open them).
