What can Nitro’s free PDF reader do for you?

Nitro’s free PDF reader offers useful productivity features beyond the typical viewing and annotation tools most other popular PDF readers provide.


  • Create PDFs from virtually any Windows application and from over 300 file formats.
  • Simply drag-and-drop files to instantly create a document.
  • Customize your PDFs with tools like custom colors, font embedding, page size, orientation, and output quality. Or, keep it simple with preset options and a customizable Home tab.


  • Add comments, address feedback, highlight, underline, or cross out text to make collaboration a breeze.
  • Quickly view PDFs, add text, and collaborate—without the learning curve—thanks to the intuitive user interface.
  • When you open a PDF with digital signatures, comments, or bookmarks, the review pane will automatically display, helping you know what to review first.


  • QuickSign any document in seconds without leaving your desk.
  • Simply scan or photograph your signature to create your own unique signature profile.
  • Create and manage Digital IDs and Trusted Contacts.


  • All PDFs created with Nitro Reader are 100% compatible with other readers—so you can securely share documents with anyone, anywhere, at any time.
  • Save PDFs directly to Box, DropBox, Google Drive, and OneDrive for fast and simple sharing with colleagues.
  • Attach PDFs to email with a single click.

And that’s not all there is to love!

Included with your download of our free PDF reader is two weeks of free access to Nitro Pro,
our full-featured PDF editor—with no risk, no commitment.

For two weeks, you’ll have the opportunity to test drive a complete PDF editor to determine
if you need more advanced features, such as editing, conversion, redaction, and more.
You may fall in love with Nitro Pro, or you may realize a PDF viewer is all you need.
Either way, you’ll still come away with the best PDF reader on the market.

Nitro products are feature-rich and extremely user friendly, and we saw a significant impact on user productivity.
