Why convert HPGL to HEIC?

HPGL is Hewlett-Packard's Graphics Language for pen plotters, a text command set of pen-up, pen-down and move instructions that CAD programs export for plotting. The pen movements are replayed by hp2xx to rebuild the drawing's linework, which is placed on a white page and rendered at 144 dpi.

HEIC uses High Efficiency Image Coding, the format iPhones and iPads save photos in, so the image is compact while staying sharp.

Frequently Asked Questions

How do I convert HPGL to HEIC?expand_more
Drop your HPGL file above and press Convert. Our servers replay the HPGL commands with hp2xx into vector EPS, turn that into a PDF with Ghostscript, and render the page as the image you chose. The result is saved as a HEIC image, ready to download.
How does the HEIC show what the HPGL plotter pen drew?expand_more
Every pen-down stroke in the file is traced by hp2xx as a vector line, so the HEIC shows the linework the plotter would draw on paper.
Why does a HPGL file go through PDF on its way to HEIC?expand_more
hp2xx writes the drawing as vector EPS, and Ghostscript converts that into a PDF. Rendering the PDF at 144 dpi keeps each line crisp in the HEIC.
What happens when a HPGL file fills several HEIC pages?expand_more
Each page is rendered at 144 dpi and saved as its own HEIC image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one HEIC file.
How compact is the HEIC made from a HPGL file?expand_more
HEIC uses High Efficiency Image Coding, which typically needs about half the space of a JPG of similar quality, so even detailed pages stay small.
Is my .hpgl file kept private?expand_more
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
