Plotter and CAD workflows often produce HPGL files, while web, publishing, or graphics tools may accept compressed SVG instead. Converting to SVGZ keeps the drawing as vector artwork and can reduce its file size for storage or transfer.
What the HPGL format is
HPGL (Hewlett-Packard Graphics Language) is a vector plotter language: its commands describe pen movement, drawing, and related plotter operations. CAD and technical drawing programs, including AutoCAD, and plotter drivers commonly create HPGL files, often with the .plt or .hpgl extension.
What the SVGZ format is
SVGZ is an SVG vector file compressed with gzip. It retains scalable paths and shapes while usually taking less storage than the equivalent uncompressed SVG. Use it when a receiving application accepts SVGZ; applications that support only SVG may require an uncompressed .svg file.
How to convert HPGL to SVGZ
Online on 101convert.com
- Upload the HPGL file on the converter page. The per-file size limit is shown there.
- Choose SVGZ as the output format and start the conversion. The conversion runs on the site’s server with Inkscape.
- Download the converted file. The page supports converting several files in one batch.
Offline with desktop software
Inkscape is free and runs on Windows, macOS, and Linux. Open the HPGL file in Inkscape, then use File → Save As and select a compressed SVG format, such as Compressed Inkscape SVG, with an .svgz filename.
Quality and compatibility
SVGZ compression does not reduce vector detail, but conversion can change how HPGL-specific pen settings, text, or plotter page dimensions are represented. Check the output’s scale, line weights, and labels in the target application. If that application rejects SVGZ, open or decompress the file and use the resulting SVG instead.
