Plotter drawings saved as PLT may need conversion when a print shop, PostScript printer, or publishing workflow accepts PS but not HP-GL files. Converting preserves the drawing as vector output when the PLT contents can be interpreted correctly.
What the PLT format is
In graphics, PLT commonly contains HP-GL or HP-GL/2 plotter commands: pen movements, lines, and other drawing instructions. CAD and technical-drawing programs, as well as plotter drivers, create these files for sending drawings to plotters. PLT files can vary in supported commands and page or plotter settings.
What the PS format is
PS is a PostScript page-description file used for printing and prepress workflows. It can describe vector paths, text, and placed raster images, and is accepted by PostScript interpreters and many print-production tools. Choose it when the receiving system requires PostScript rather than plotter commands.
How to convert PLT to PS
Online on 101convert.com
- Upload the PLT file on the converter page; multiple files can be added for batch conversion. The page shows the per-file size limit.
- Choose PS as the output format and start the conversion. It runs on the server with Inkscape.
- Download the resulting PS file or files.
Offline with desktop software
Inkscape is free and available for Windows, macOS, and Linux. Open the PLT using File → Open; if an import dialog appears, check the page size and scale before confirming. HP-GL import depends on the HPGL input extension and its required components being available in the installation. Then use File → Save a Copy…, select PostScript (.ps) as the format, choose a filename, and save.
Quality and compatibility
HP-GL files describe plotter actions, so the imported result depends on which commands the importer supports and how it interprets units, pen widths, and page bounds. Inspect the drawing after import, especially its scale and clipping, before exporting. PostScript does not retain the original plotter commands, and features unsupported by the importer may be missing or rendered differently.
