This article explores Nitro PDF Reader in depth, examining its core features, user experience, strengths and weaknesses, and how it compares to other PDF solutions on the market.

What is Nitro PDF Reader?

Nitro PDF Reader is a free multi-functional PDF application developed by Nitro Software, a global leader in PDF and electronic signature solutions . Unlike basic PDF viewers that only allow you to open and read documents, Nitro Reader provides a suite of tools for interacting with and managing PDFs, including creation, annotation, conversion, and form filling.

The software was designed to be a more affordable alternative to Adobe Acrobat, providing many of the same professional-grade features without the high price tag . The free version covers essential document workflows for most users, while paid versions like Nitro Pro and Nitro PDF Pro offer advanced editing, OCR, and e-signature capabilities for business users .

Key Features of Nitro PDF Reader

Nitro PDF Reader’s strength lies in its extensive feature set, which bridges the gap between a basic reader and a full-featured editor.

PDF Creation and Conversion

One of the most powerful aspects of Nitro PDF Reader is its ability to create PDFs from over 300 different file formats . This is achieved through several methods:

• Nitro PDF Creator: A virtual printer driver that allows you to convert any printable document to PDF. Simply select “Nitro PDF Creator” from the print menu in any Windows application to save it as a PDF .
• Drag-and-Drop Creation: You can create a PDF instantly by dragging any file onto the Nitro Reader desktop icon, which automatically opens the resultant PDF in the application .
• Create from File: The software offers in-application functionality to create PDF from any file, with predefined profiles for different use cases like Web-ready or Print-ready documents .

Annotation and Collaboration Tools

Nitro PDF Reader is equipped with a comprehensive annotation toolkit that facilitates document review and collaboration :

• Markup Text: Highlight, cross-out, and underline text, allowing you to draw attention to sections requiring revision. You can also add comments to these highlights .
• Type Text Anywhere: This tool lets you add text directly onto the pages of a document, in whatever font, size, and color you specify—useful for filling out static forms or expanding on content .
• Comments Pane: An easily digestible list of all markups, comments, and annotations within a document. Users can reply to, sort, and manage comments, facilitating easy-to-follow document revision .
• Snapshot Tool: The Snapshot tool allows you to select any on-screen area, regardless of content, and copy it directly to your Clipboard for quick reuse of images or text .

Extraction Capabilities

The software provides useful tools for extracting content from PDFs:

• Extract Images: Save all images contained in a PDF document as separate files in formats like BMP, JPG, PNG, and TIF. The intelligent extraction can choose the most appropriate format for each image .

• Full-Screen View: For the closest experience to paper, Full Screen mode displays the PDF with no extraneous functionality or content .
• Search Functionality: Quickly find text in larger documents with keyboard shortcuts or the Find box .

Forms and Signatures

The software’s form and signature features represent a significant advantage over basic PDF readers:

• Fill and Save Forms: Unlike some solutions that force you to print or scan filled forms, Nitro Reader allows you to save any content entered in PDF form fields to retain an electronic copy .
• Fill Static Forms: Even if a PDF wasn’t properly set up as a form, the Type Text tool allows you to fill it out .
• QuickSign Tool: Add a scanned image of your signature, then place it anywhere in the document. The signature can be resized and moved before embedding .

Nitro PDF Reader vs. Alternatives

Nitro PDF Reader vs. Adobe Acrobat Reader

Adobe Acrobat Reader is arguably the most well-known PDF reader, offering a free tier for basic viewing and annotation. The comparison between Nitro and Adobe reveals some important distinctions:
