Collaborate & Review

  • Review and collaborate on files faster with Nitro Pro. Markup and share feedback on text documents, presentations, creative designs, and technical drawings.

  • The easy way to collaborate

    Nitro Pro works well with others. Collaborate quickly and easily with a wider group of people.

    Collaborate with Adobe users.
    You’re not limited to working with Nitro Pro users–your comments look and work the same in other PDF viewers. You can view comments from Acrobat and Reader users, and they can view yours.
    Add feedback without (accidentally) changing content. Unlike commenting and reviewing in Microsoft Word, the annotations you add to PDF files don’t modify the page content and can easily be removed.
     
    Directly reply to comments added by other reviewers.
     
  • Review text and add feedback

    Use text highlighting, pop-ups and other ways to share your feedback.

    Sticky notes.
    Place sticky notes anywhere on a page and add your feedback.
    Highlight and mark up text.
    Highlight, cross out, and underline text just like you would on paper and attach comments directly to your mark ups.
     
    Text boxes and call outs.
    Add text that appears alongside or on top of page content. In addition, call out arrows can highlight text more precisely.
    Type text directly on pages.
    Use the Type Text tools to add annotations or quickly fill out electronic forms.
  • Mark up pages with drawing annotations, stamps and file attachments

    Go beyond just commenting. Use drawing annotations to share feedback on any part of the page.

    Freehand pencil.
    Draw and mark up pages just like you would on paper and then attach text-based feedback to each mark up.
    Drawing shapes.
    Use pre-defined shapes (line, arrow, rectangle, oval, polygon, polygon line and cloud) to add neat, consistent drawing mark ups.
     
    Stamps.
    Add highly visible annotation stamps (like 'Draft,' 'Final,' and 'Approved') to page. Even custom-make your own reusable stamps.
    Attach files.
    Easily attach and embed any type of electronic file inside your PDF document.
  • View, organize, print, summarize

    Handle your document review cycles through easy-to-use comment management tools.

    View, sort and manage all comments. Use the Comments panel to view, arrange and organize all comments.
    Print with markup.
    Print PDF files with visual annotation mark ups displayed just as they appear in Nitro Pro.
     
    Print and summarize comments.
    Summarize comments and view them alongside each page as a printed copy.
