Convert a file to NPFX
To convert other file formats to the "Firewall Configuration File" file type, you need software like Norton Internet Security or a similar tool.
About NPFX files
.NPFX files store user-defined firewall rules, trusted application lists, and network security policies for Norton Internet Security. They are generated when a user backs up or exports their personal firewall configuration to migrate settings between devices or recover them after a system reinstall.
These files are created and managed exclusively by Norton security products, originally developed by Symantec.
The major disadvantage of the .NPFX format is that it is a proprietary, closed format. The data structure is heavily tied to the specific version of the Norton engine that created it. Users face massive challenges when trying to migrate their carefully crafted firewall rules to competing antivirus software or when trying to read the policies in a human-readable format. Traditional online converters fail entirely because this is not a standard document, but rather a specialized software configuration binary.
Directly converting an .NPFX file to standard readable formats like XML, JSON, or TXT is rarely possible without using Norton's own internal export tools. Most of the rule syntax is proprietary and locked.
Because this file format is difficult to open or convert, often only the original software can properly read or export the data.
Convert.Guru analyzes your NPFX file, detects the exact format, and lets you read the text inside.

The NPFX Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NPFX converter.
