Fz File Viewer

Here’s a write-up for "FZ File Viewer" — suitable for a software documentation page, a GitHub README, or a tool listing.

Most Common Usage: Electronics schematic and PCB design.

If you have a file ending in .fz, it is a Fritzing Sketch created by the open-source Fritzing software. This file contains the layout of an electronic circuit, including the breadboard view, schematic view, and PCB view. fz file viewer

How to view/open it:

  • Text/Code View: Because .fz files are saved in an XML format, you can right-click the file and select "Open With" > "Notepad" (Windows) or "TextEdit" (Mac). This won't show you the visual circuit, but it allows you to read the code, parts lists, and connections textually.
    • fz-viewer-cli --info project.fz
# Output: Archive type: Fritzing sketch (ZIP)
#         Files: 12
#         Contains: breadboard.svg, schematic.svg, pcb.svg, metadata.xml

    fz-viewer-cli --extract project.fz --output ./exported

    Before diving into viewers, you must understand that the .fz extension is polymorphic. Depending on the context, it can represent three very different file types: Most Common Usage: Electronics schematic and PCB design

    As a last resort, developers or advanced users can open an FZ file in Notepad++, Sublime Text, or VS Code. This is not a true "viewer" because the data will appear as binary or XML gibberish. However, scanning the first few lines for headers like PK (ZIP) or FZR (Fritzing Raw) can help you identify which dedicated viewer to use.

    The FZ File Viewer is a lightweight, cross-platform utility designed to open, parse, and display the contents of .fz files — a compressed format commonly associated with Fritzing (an open-source electronics prototyping tool) and, in some cases, custom archive formats.
