Acrobat Reader makes it easy to annotate and comment on PDF documents. With Reader on your desktop, you can:

• Annotate PDFs using sticky notes
• Type text directly onto the page
• Highlight, underline or use strikethrough tools
• Draw on the screen with the freehand drawing tool.

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

Yes. The Fill & Sign tool, powered by Adobe Acrobat Sign, automatically recognises whether your PDF has fillable form fields or not and offers an intuitive filling experience to complete the job quickly and easily.

With a fillable form, it’s easy to type your answers, sign your signature or select from drop-down lists, then save your completed document.

When working with simple PDFs that haven’t been optimised 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, signed form to others.

Yes. Acrobat Reader provides a limited number of signatures you can request using the Fill & Sign tool, without purchasing a subscription to Acrobat Pro, Adobe Acrobat PDF Pack or Adobe Acrobat Sign.

If you exceed the allowance of free signature transactions, you can subscribe to one of the various Document Cloud solutions to request even more signatures.

Existing customers of Acrobat Sign can use the Acrobat Sign mobile app to do the same on Android or iOS or Windows. You can also send files for signature using your web browser.

Protected Mode is Adobe's primary defense-in-depth security strategy for mitigating and preventing security vulnerabilities. It protects you by limiting what malicious files can do and access. It runs silently in the background while protecting your hardware and data.

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 organisations 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 in our internal culture, software development, and 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.
