A pen plotter or cutting workflow may require HP-GL files and reject a Windows Metafile. Converting WMF to PLT turns the drawing into plotter commands that compatible equipment or software can read.
What the WMF format is
WMF (Windows Metafile) is a vector graphics format that stores drawing operations, and can also contain bitmap data. Windows applications, including Microsoft Office and graphics programs such as CorelDRAW, have created or used WMF files; they commonly appear in older documents and Windows-based graphics workflows.
What the PLT format is
In graphics workflows, PLT usually means a plotter file containing HP-GL or a related HP-GL/2 command stream. Plotters and some cutters use these commands to move a pen or tool along paths. PLT is useful when the receiving device or application specifically supports HP-GL; it is not a general-purpose image format.
How to convert WMF to PLT
Online on 101convert.com
- Upload the WMF file using the converter on this page. Multiple files can be added for batch conversion; the per-file size limit is shown on the page.
- Start the conversion and wait for the PLT result.
- Download the converted file.
The conversion runs on the site’s server with Inkscape.
Offline with desktop software
Inkscape is free and runs on Windows, macOS, and Linux. Open the WMF, then use Extensions → Export → Plot (the exact label can vary by installed extension). Choose the HP-GL/plotter output options, apply the extension, and save the generated plotter file with a .plt extension if the dialog does not set it automatically. If the Plot extension is unavailable, use an Inkscape package that includes HP-GL output.
CorelDRAW is a commercial option for Windows. Open the WMF, choose File → Export, select HPGL Plotter File as the file type, set the plotter options offered by the export dialog, and save as .plt.
Quality and compatibility
PLT output represents plotter movements rather than preserving all WMF appearance data. Gradients, transparency, embedded bitmaps, and some fills may not transfer as expected; check the output in the target plotter software. Text can depend on available plotter fonts, so convert text to paths before export when the software offers that option. Confirm page size, scale, and pen settings against the destination device, since HP-GL variants and supported commands differ between plotters.
