Top features:

IMPROVED Comment using the PDF annotator
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.

IMPROVED Fill out forms
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.

IMPROVED Sign files with e-signatures
No need to print documents before you sign them. With Reader XI, it’s simple to add your electronic signature to PDFs — and just as easy to get them signed by others.

View and annotate PDF documents

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.

Read the way you like
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 for words and phrases
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.

Protect your system
Help safeguard your software and data from malicious code and keep unauthorized users from viewing private information with Protected Mode.

Fill, sign, and send PDF forms

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.

Sign PDF forms
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.

NEW Get forms signed by others
Email your signed PDF form, or send it to others to e-sign using the Adobe EchoSign® online service from within Reader XI. Just open a free or paid account.
