Plotter drawings saved as PLT often need conversion when a Windows application or document workflow accepts Windows Metafile (WMF) but not HP-GL files. WMF keeps supported drawing elements as editable vector graphics rather than requiring a raster image.
What the PLT format is
In graphics, PLT usually means a plotter file containing HP-GL or a related plotter language. It stores drawing instructions such as pen movement, lines, and pen selection. CAD and illustration programs, including AutoCAD and CorelDRAW, can create PLT files for plotters; PLT files also turn up in engineering drawings and legacy print workflows.
What the WMF format is
WMF (Windows Metafile) is a Windows graphics format that stores drawing operations and can be scaled without the pixelation associated with enlarging a bitmap. It is useful when placing vector artwork in Windows documents or applications that support WMF. It is a legacy format, so newer formats such as SVG or PDF may be better choices when the receiving software supports them.
How to convert PLT to WMF
Online on 101convert.com
- Upload the PLT file on the 101convert.com conversion page.
- Choose WMF as the output format and start the conversion. The page can convert multiple files in a batch; its per-file size limit is shown there.
- Download the converted WMF file or files.
The conversion on this page runs with Inkscape.
Offline with desktop software
Inkscape is free and open-source, with versions for Windows, macOS, and Linux. Open the PLT using File → Open; if an import dialog appears, confirm the plotter settings. Then use File → Save a Copy, choose Windows Metafile (.wmf) as the format, and save. The available import or export formats can depend on the Inkscape build.
CorelDRAW is a commercial option for Windows. Use File → Import to open the PLT, then File → Export and select WMF as the output format.
Quality and compatibility
PLT records plotter commands, so the result depends on how the converter interprets the file’s units, page dimensions, pen assignments, and supported HP-GL commands. Check the WMF’s scale, orientation, line widths, and colors after conversion; unsupported commands or pen settings may be omitted or represented differently. WMF is also less suitable than SVG or PDF for workflows that need modern cross-platform vector exchange.
