Questions & Answers
HP files: Frequently Asked Questions
What are HP files?
HPGL (Hewlett-Packard Graphics Language) is a legacy vector format widely used in technical drawing, CAD applications, and cutting/plotting machinery. Developed by Hewlett-Packard, this format stores 2D vector graphics as a series of plotter instructions, making it perfect for large-format printing, CNC machining, and archival technical drawings.
With reaConverter, you can seamlessly convert HPGL files to modern formats like PDF, SVG, or DXF while maintaining precise linework, scaling, and geometric accuracy. Whether you're updating vintage blueprints, preparing designs for digital cutting plotters, or migrating legacy technical data, reaConverter ensures smooth compatibility across platforms and devices.
