Free Open-Source Gerber Viewer for Windows, Mac & Linux
Gerbv is a free, open-source viewer for Gerber RS-274X, Excellon drill, and CSV pick-and-place files. Stack your layers, measure your board, and check your fabrication files offline before you order. New to all this? Start with our Gerber viewer guide.
What Gerbv Does
Gerbv is a viewer first. It renders fabrication data so you can verify what your EDA tool exported — it does not route boards, and it does not replace your fab house checks.
Layer Stacking & Transparency
Load several files on top of each other, toggle layers, change colours, and use Cairo transparency mode to see which layers sit underneath others.
Measurement & Reports
Measure distances on the displayed image, and inspect report windows with statistics on the Gerber and drill codes used, plus aperture-usage reporting.
Export & Conversion
Export to PNG, PDF, PS, SVG and DXF, or translate between RS-274X and Excellon formats. Command-line export and panelization are also supported.
Limited Editing
Select objects to view their properties or delete them. That is the honest extent of editing — there is no track routing, layout editing, 3D view, or design-rule checking.
Works Offline
Gerbv is a native desktop application based on GTK 2 and Cairo. Your fabrication files stay on your own machine.
Free & Open Source
Licensed under GPL-2.0-or-later, with source code on GitHub (270+ GitHub stars). Use it for personal, educational and commercial verification work at no cost.

A Classic Tool, Revived in 2026
Gerbv began as part of the gEDA project and has a long history as a free Gerber viewer. On SourceForge, its historical project page records a 4.6 out of 5 rating from 26 ratings, and 1,247,968 all-time downloads since 2001 — historical context for the project, not a rating of this website.
After about two and a half quiet years, the project returned in 2026 with three releases in three weeks: v2.11.0 (February 28, 2026) rebuilt the build system on CMake, v2.12.0 (March 8, 2026) built DXF export in on all platforms and optimised SVG export, and v2.13.0 (March 20, 2026) shipped the first release with native Windows and macOS builds, including an NSIS-packaged Windows installer.

Frequently Asked Questions
Is Gerbv completely free to use?
Yes. Gerbv is free and open-source software licensed under GPL-2.0-or-later. You can use it for personal, educational and commercial PCB verification without fees.
What file formats does Gerbv support?
Gerbv views Gerber RS-274X files, Excellon drill files and CSV pick-and-place files. It does not support legacy RS-274D files.
Which operating systems does v2.13.0 run on?
The v2.13.0 release provides 64-bit Windows builds (Windows 10 is the tested target), a macOS zip — the first macOS build included in a release — and Linux packages for Debian 13, Ubuntu 22.04 and Fedora 43.
Can Gerbv edit my PCB design?
Only in a limited way: you can select and delete objects, translate formats on export, and panelize boards from the command line. Gerbv is a viewer for fabrication data, not a PCB layout editor, and it has no 3D view or design-rule checking.
