A plotter or other device that accepts HPGL cannot use a WEBP image as its plotting instructions. Converting the image is useful when that device or its software requires HPGL, but raster artwork may need to be traced into paths first.
What the WEBP format is
WEBP is a raster image format that supports lossy and lossless compression, transparency, and animation. It is common on websites and is created or exported by web browsers, image editors, and graphics tools. Its pixels store image appearance, not plotter movement instructions.
What the HPGL format is
HPGL (Hewlett-Packard Graphics Language) is a command-based format for pen plotters. Its commands control pen movement, drawing, and pen selection, making it suitable for sending line-based graphics to compatible plotters and other equipment that accepts HPGL. It describes paths rather than a grid of pixels.
How to convert WEBP to HPGL
Online on 101convert.com
- Open the WEBP-to-HPGL converter page on 101convert.com and upload the image. Several files can be converted in one batch; check the per-file size limit displayed on the page.
- Start the conversion and wait for it to finish.
- Download the resulting HPGL file and check it in software compatible with your plotter.
Offline with desktop software
Inkscape is free, open-source software for Windows, macOS, and Linux. Since WEBP is raster data, trace it to paths before exporting for a plotter:
- Open the WEBP image in Inkscape, select it, then choose Path → Trace Bitmap. Choose a tracing mode suited to the artwork and apply the trace.
- Move the new paths aside to verify the trace, then delete the original raster image. Choose File → Save a Copy and select the HPGL/plotter format, if available in your Inkscape build. Save the output as
drawing.hpgl.
Quality and compatibility
Tracing converts visible shapes into paths; it does not preserve the original pixels, photographic detail, or smooth color gradients. Logos and high-contrast line art generally trace more cleanly than photographs. Inspect the HPGL output and confirm its scale, pen behavior, and command compatibility in the target device’s software before plotting.
