In a perfect world, we’d all have a feature-packed, free PDF editor that can do everything you might need whenever you’re given an important document to fiddle with.
Android: I hate dealing with PDFs. I understand why they’re necessary, but loading them is a pain and editing them is even worse. So, Adobe’s news that Acrobat Reader can edit PDFs stored in your Dropbox is a godsend.
Chrome: Notable PDF is a Chrome extension lets you edit PDF files from within the Chrome browser. This extension works offline, too, so it’s a great add-on for Chromebooks.
