Nitro PDF Reader has long been our favourite Windows PDF tool at Lifehacker AU, offering bloat-free options for both viewing and editing PDF files. Version 2.1 makes a bunch of improvements, including adding selection tools to its browser plug-in and expanding the zoom option to offer sizing between 1 per cent and 6400 per cent.
I must admit that I'm not a major user of the browser plug-in — I'm happy to let Chrome handle basic viewing and then use Nitro when I'm dealing with larger documents or editing tasks — but it's a nice enhancement. Other changes include thumbnail previews for 64-bit Windows users and general performance enhancements. The upgrade is being rolled out this week.
