Reader makes it easy to annotate PDF documents.

The same commenting tools are also available in Acrobat Reader for mobile.

Yes. The Fill & Sign tool automatically recognizes whether your PDF has fillable form fields or not and takes you to an intuitive filling experience, powered by Adobe Sensei, to get the job done quickly and easily. With a fillable form, it’s easy to type your answers or select from drop-down lists, then save your completed form. When working with simple PDFs that haven’t been optimized with form fields, you can click anywhere and type answers right onto the form – or you can accept suggestions from your personal autofill collection. When you’re done, you can save your changes and send the completed form to others.

Using the Adobe Acrobat Reader mobile app, you can do the same tasks on your iOS or Android devices too. To download the Adobe Acrobat Reader mobile app, visit Google Play or the iTunes App Store.

To protect you and your organization from malicious code that attempts to use the PDF format to write to - or read from - a computer’s file system, Adobe delivers an implementation of "sandboxing" technology called Protected Mode. Enabled by default in Acrobat Reader, Protected Mode protects against attackers who attempt to install malware on your computer system and blocks malicious individuals from accessing – and extracting – sensitive data and intellectual property from your computer or corporate network.

Security settings and access privileges for a PDF file cannot be set in Reader; however, they can be set using Adobe Acrobat software. With security settings, authors can define who can open, view, print, copy, or modify a document. These capabilities help organizations protect the confidentiality of sensitive information. With access privileges, authors can define a password that users will need to open the document, or they can use a certificate ID to encrypt the document so select recipients can open it by entering their own, unique certificate IDs.

Yes. At Adobe, security practices are deeply ingrained into our internal culture, software development, as well as service operations processes. Whether related to identity management, data confidentiality, or document integrity, Adobe Document Cloud services employ leading-edge security practices to protect your documents, data, and personal identifiable information to the highest degree possible.
