Why convert PLO to WebP?
PLO is a plotter output file holding HPGL-style vector instructions, written when drawings are sent to a pen plotter or cutter. The file's pen movements are replayed by hp2xx to rebuild the drawing, which is placed on a white page and rendered at 144 dpi.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert PLO to WebP?
Drop your PLO file above and press Convert. Our servers replay the PLO's plotter 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 compact WebP image, ready to download.
Which language inside a PLO file does the WebP converter read?
PLO files carry HPGL plotter instructions, so they are read with hp2xx, the same interpreter used for PLT and HPGL files.
What background does the PLO drawing sit on in the WebP?
The linework is rendered on a plain white page, the way the drawing would look plotted on paper.
What happens when a PLO file fills several WebP pages?
Each page is rendered at 144 dpi and saved as its own WebP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one WebP file.
How much smaller is the WebP from a PLO file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
Is my .plo file kept private?
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.
