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.


  • Add comments, address feedback, highlight, underline, or strike-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.
  • Password-protect your documents to keep signatures safe and secure.


  • All PDFs created with Nitro Reader are 100% compatible with other readers—so you can securely share documents with anyone, anywhere, at any time.
  • Colleagues can also create multiple QuickSign profiles, making it easy to share back and forth between teams and businesses.

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 isn’t relaxing its efforts to help people and organizations improve their digitized workflows. Nitro Pro is now fully integrated with Nitro Sign, making it easier than ever to create a document, share it, and get it signed. As a whole, document workflows just feel simpler and more seamless."
