Nitro PDF Overview
Nitro PDF (Nitro Pro) is a commercial PDF productivity application for Windows (and macOS) that provides a full set of tools for creating, editing, converting, and signing PDFs, positioned as a more affordable alternative to Adobe Acrobat with a familiar, Office-like interface. It lets you edit text and images, convert PDFs to and from Microsoft Office formats, combine and organize documents, run OCR, fill and create forms, and apply electronic signatures, with batch processing for handling many files. It is aimed at businesses and individuals who want comprehensive PDF editing without a subscription-only model. The offline installer bundles everything Nitro PDF needs, so installation completes without a connection. It also offers redaction and document-comparison tools, which help when reviewing changes between versions of a file.
