Comment, review, and collaborate

Stop trying to work with PDF and start making PDF work for you. Digital documents are transforming the way we all work together, but premium collaboration tools have never been available in a free PDF reader. Until now.



Bring the meeting into the document

With tools to highlight, cross-out, and underline text, as well as the ability to add sticky notes anywhere within a document, Nitro Reader will have you looking at your red pen in a very different light.

Join the collaboration process and start replying to comments and markups, while retaining a comprehensive record of the entire review cycle. View everyone's contributions in the Comments panel — involve as many contributors as you need, on as many pages as you have, finally presented in a way that makes sense.

The ease of pen and paper

Need to expand on a particular paragraph, or add text that wasn't included in first place? Use Nitro Reader to type text directly onto the page, anywhere you need to.

Just click, and start typing.

There's no need for the originator to enable any functionality, and you can use all of this with any PDF you receive.

Now, when someone asks for your feedback, you can actually provide it.
