HGL files: Frequently Asked Questions
What are HGL files?
The .hgl file extension represents a variant of the HP Graphics Language (HPGL) format, a vector-based file type developed by Hewlett-Packard for controlling pen plotters and technical drawing equipment. These text-based files contain sequential plotting commands that direct the movement of plotter pens, including instructions for line drawing, text placement, and device control. Functionally equivalent to the more common .hpgl extension, .hgl files were particularly prevalent in early CAD systems and engineering workflows during the 1980s and 1990s. The format's ASCII structure makes it both human-readable and machine-interpretable, though modern usage is primarily limited to legacy system maintenance and archival conversion projects. Contemporary software tools can typically process .hgl files alongside other HPGL variants for conversion to modern vector formats like SVG or DXF.
