Nitro PDF Pro is a Mac PDF editor for reading, editing, annotating, converting, signing, and securing PDF documents in everyday work.
What is Nitro PDF Pro?
Nitro PDF Pro is a native Mac PDF editor that helps people read, edit, annotate, convert, sign, and organize PDF documents. It is designed for everyday document work such as marking up contracts, filling forms, combining files, correcting text, and preparing PDFs for sharing. The app supports common office workflows with tools for comments, page management, OCR, redaction, and document security controls. It also fits users who need to create PDFs from other files or export PDF content into editable formats for further work. Nitro PDF Pro is published by Nitro Software, Inc. and is used by individuals, students, and teams who want fuller PDF editing on macOS than the built-in Preview app provides.

Safety overview
Status: Safe
Nitro PDF Pro is legitimate PDF-editing software for macOS. It normally needs access to files you choose so it can open, edit, save, sign, export, or secure documents, which is expected for this type of app. Documents you open may contain sensitive personal or business information, so use trusted files and review redaction or export results before sharing them. If you no longer use the app, removing it only affects Nitro PDF Pro and its local support files.
Recommendation: Keep Nitro PDF Pro if you use it for PDF editing, forms, signatures, OCR, or document review on your Mac. If you have switched to another PDF tool and do not need its saved settings or helper data, you can remove the app and then clean up its leftover support files.
