Many think that a PDF is static… you can’t do anything but read it. But here are two Google Chrome Apps/Extensions that allow you to copy text from a PDF, annotate, draw on, comment, “white out”, underline, and more: Kami and DocHub.
To start, open a PDF from your Google Drive. Above the PDF, click on “Open with…”, choose “Connect More Apps” and search for Kami and/or DocHub. (You may have to ask your GAFE administrator to ok these extensions in your domain.) Allow it to connect to your Google Drive. Now, click open with… and choose either Kami or DocHub. They both allow you to do basic annotations but they also each have tools that the other does not. For example, DocHub will allow you to insert blank fields (text, checkboxes, signatures, initials, etc) and Kami does not. DocHub’s free version allows you to legally digitally sign up to 3 documents a month and you can have others digitally sign the same document as well. Of course, there are Pro (paid) versions of both Kami and DocHub for anyone who wants more than the basics.
Here is a quick overview of Kami:
