The optional online services include converting PDFs to Word or Excel documents and creating PDFs using Adobe CreatePDF online. Reader doesn't lack support, either, starting with the sort of extensive Help file you'd expect from an Adobe product.

Under the Edit menu, entries labeled Protection, Analysis, and Accessibility let us manage security settings, check document accessibility, and analyze data using the Object Data Tool and Geospatial Location Tool. A Tracker tool monitors updates to Reviews and Forms. Reader has some extras that stripped-down competitors can't match, such as its Read Out Loud tool, which can read documents to you if you have sound capability. We could highlight text, add Sticky Notes, take a Snapshot, and attach Comments. We could also Print our document or e-mail it as an attachment or via Adobe SendNow. Clicking the Sign icon on Reader's toolbar let us digitally sign documents by adding text or attaching a signature via a wizard. Reader rendered each document with high detail and faithful color reproduction. We clicked Open and browsed to a folder full of PDFs we use for testing. Reader X's familiar interface opens with a quick-start file manager from which we could open a recent file or log in to an existing Adobe Online account. With it you can view and annotate all PDF files, sign documents electronically, and access optional Adobe Online subscription services directly from inside its interface. We looked at the latest version of Reader, Adobe Reader X. Despite competition from simpler tools, Reader remains the standard the others are judged against. To open, view, and edit PDFs, you need a PDF reader - for example, Adobe's free Reader.

PDF, the file format that carries the business world on its back, is everywhere, from product manuals to legal documents. Adobe developed the Portable Document Format to standardize electronic document handling.
