Pro Digital signatures
PDF Studio Viewer is the only free PDF viewer for Linux that recognized digital signatures from docusign in a way that lets you easily verify the signatures.
Pro Advanced print & search options
PDF Studio Pro is a really useful PDF editor. This is more like Adobe Acrobat earlier versions, in terms of look and feel. That’s user friendly. Command icons are clear with tooltip already written. Menu is elaborated well break-up. Also, all the functions seems to be available.
Pro Measurement tools
Pro Loupe tool
Pro As of 2018 supports text, markup & graphical annotations, as well as form filling
Pro User-friendly advanced printing
The easiest software I found for printing multiple pages on Linux Mint. All other software require inputting pages by numbers, here, you can just select the ones you want to print, choose the format of multiple pages (horizontal/vertical) and it all comes with a beautiful gui. I used to love adobe and foxit on windows, but those programs suck on linux.
Pro The Only Complete PDF editing/viewer tool available for all platforms (Windows, MacOS, Linux, Unix)
It GUI is user friendly and well designed with its ribbon menu. It's actually very similar to what you can find in a MS Word or Adobe Pro environment. It has all the features you can imagine for commenting/marking the PDF, creating forms, and editing PDF files. It is available on all platforms: Windows, MacOS, AND LINUX.
