The digital trend these days is about doing everything—even the littlest things, online. You want to do everything you do on the desktop on the Internet, charge-free, plug-in-free and software-free.
If you’re one of the many who are looking to expand your PDF work online, you might want to check out A.nnotate.
A.nnotate is a handy online service that lets you annotate your PDF files. The service is perfect if you review PDFs on a regular basis, need a backup solution for desktop PDF software or need constant access to annotation functionality.
Whether you think about it or not, most of the web content you save in a PDF is excess material you don’t ever really need. Did you really need those 7 extra paragraphs? The picture of an ugly toad in the corner? The web page ads?
