Gerbolyze is a tool for rendering black and white raster (PNG) images directly onto gerber layers. You can use this to put art on a PCB's silkscreen, solder mask or copper layers. The input is a black-and-white PNG image that is vectorized and rendered into an existing gerber file. Gerbolyze works with gerber files produced with any EDA toolchain and has been tested to work with both Altium and KiCAD.
First, upload a zip file containing all your gerber files. The default file names used by KiCAD, Eagle and Altium are supported.
