An is a Fritzing document. It is an XML-based file format that stores the information for a single electronics design. Unlike standard image files (JPG or PNG), FZ files are dynamic: they contain data for three distinct, linked views of your project:
In older versions of Fritzing, the .fz extension was used to save electronic circuit designs, including breadboard layouts, schematic diagrams, and printed circuit board (PCB) views.
Drag the Fritzing app to your applications folder. Open Within: Open the app and use Cmd+O to open the file. Opening FZ Files on Linux

If you have an FZ file and need to see what’s inside, follow these steps:
: Most commonly, an FZ file is a circuit design created in Fritzing , an open-source tool for electronics. It contains the XML data for breadboards and schematics.
The most direct and reliable "FZ file viewer" is the Fritzing application itself. As an open-source tool, it is designed specifically for hobbyists and professionals to document their breadboard prototypes and transition them into PCB layouts. How to Open FZ Files in Fritzing: Drag the Fritzing app to your applications folder
The absolute best way to open, view, and modify an FZ file is by using the official software. Since the file format was built specifically for this ecosystem, Fritzing will render the breadboard views, schematic diagrams, and PCB layouts perfectly without errors. Platform: Windows, macOS, and Linux.
If double-clicking the FZ file opens the wrong program (like a media player or browser), you need to reset your system's file associations:
