Technical note

HPG to PDF: what carries over and what does not

HPG drawings carry layers, line weights, and a drawing scale, and PDF records how the drawing looks on a page. Layout, paper size, and scale are decided at conversion time, so set them deliberately: a drawing that reads correctly on screen can come out unusable if the scale is left at its default.

reaConverter handles HPG files flawlessly. I use it to convert plot files to PDF for approvals, and the output is always accurate. The automation through Watch Folders and command-line is a big plus for speeding up our workflow.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

HPG to PDF Conversion

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics.
