Open Source Gerber Viewer

A free, open source tool to quickly visualize your Gerber and Excellon drill files directly in the browser. Upload your files below to get a visual overview of your PCB design.

This tool is intended to give you a quick visual idea of your Gerber/drill file set. It is not a manufacturing tool and should not be used for production verification.

Privacy

We do not store any of your data. Your Gerber files are sent to the server to be rendered and, if you ask for it, exported, but they are processed in memory only and never saved or stored.

3D model

Press STEP to download the board outline as an ISO 10303-21 solid — the bare board as a mechanical part, ready to drop into CAD when you design an enclosure around it. It carries the drilled holes and the mouse bites on a break-off tab, and both faces are labelled so you can tell top from bottom.

Board thickness is the one number no Gerber file carries, so state it in the box next to the button; it defaults to a standard 1.6 mm board.

Open Source

This viewer is part of the delta-gerber library, an open source Java library for parsing and rendering Gerber (RS-274X) and Excellon drill files.

The source code is available on GitHub: github.com/Delta-Proto/delta-gerber

Run it locally

You can download the standalone JAR from the latest release and run it on your own machine:

java -jar delta-gerber-1.5.1-jar-with-dependencies.jar

The viewer will open at http://localhost:9380.

Integrate into your own project

The library is available as a Maven dependency. Add it to your project to parse Gerber and drill files, generate SVG renderings, or build your own viewer.

See the GitHub repository for documentation and usage examples.
