With Adobe Reader XI, you can do even more than open and view PDF files. Now, it's easy to add annotations to your document using a complete set of commenting tools.
Reader XI comes with a full set of commenting tools. So you can add sticky notes, highlight text, and use lines, shapes, stamps, and a typewriter tool to place comments anywhere on your PDF document.
Choose reading mode to fit more content on the screen or two-up mode to view page spreads. Use familiar keyboard shortcuts like print, zoom, and find within the browser.
Search one or more PDF files at the same time to find every instance of a word or phrase — whether it's contained in page content, annotations, bookmarks, form fields, or metadata.
Help safeguard your software and data from malicious code and keep unauthorized users from viewing private information with Protected Mode.
Get documents signed in minutes instead of hours. Use Reader XI to complete, sign, and return a PDF form — and save a digital copy for your records.
Say goodbye to paper forms. Type your responses right on the PDF form, or click through and fill in the form fields. Then save and submit. That's really all there is to it.
When you need to sign a PDF form, it’s easy to add your e-signature. Simply type it in, add a hand-drawn signature, or import a scanned image of your signature.
