14 Best Free Gerber Viewer Software For Windows

Here is a list of Best Free Gerber Viewer Software for Windows. These software let you open and view Gerber files (GRB files) with the help of their extensive tool set. Some of the software listed below are Gerber editor software as well, and let you view as well as make changes to Gerber PCB designs.

PCB design in Gerber files are made of various layers of components, copper, traces, etc.; these layers can be separately viewed with these Gerber viewer software. You can zoom, rotate, flip, and move the designs for enhanced view. Some of these software also let you view top and bottom view of PCB design layers.

Another feature that most of these software have is that they let you find the distance between two components in mm/cm/inches.

Use these Gerber file viewer software to export the design in various formats, like: SGV, PDF, PNG, PDF, JPEG, etc. Take a print out of the design if you want.

To know more about these software to view Gerber files, read the brief description of the listed software. You will also know how to open Gerber files with the listed software.
