About formats

WPG (WordPerfect Graphics) is a mixed vector/raster image format developed by WordPerfect Corporation and introduced with WordPerfect 5.0 on May 5, 1988. The format was designed to provide a native graphics capability for WordPerfect documents, supporting both vector drawing elements (lines, curves, polygons, text with font specifications, and filled shapes) and embedded raster images in a single file. WPG exists in two major versions: WPG1, which supports 1-bit and indexed color rasters up to 256 colors with optional run-length encoding compression, and WPG2, introduced later, which added true-color (24-bit) support, OLE object embedding, and enhanced vector capabilities. The vector portion of WPG files stores resolution-independent drawing commands that can be scaled and printed at any output device's native resolution, while the raster portion handles photographic and scanned content. During WordPerfect's peak market dominance in the late 1980s and early 1990s, WPG was one of the most commonly encountered graphics formats in business and legal document workflows, used for logos, diagrams, letterheads, and clip art. One advantage is the hybrid vector/raster capability: WPG could combine scalable line art with photographic imagery in a single file at a time when most formats handled only one or the other, making it practical for the mixed-content graphics typical of business documents. Continued accessibility is another strength — WPG files remain readable by LibreOffice, Corel's current software suite (which inherited WordPerfect), ImageMagick, XnView, and Inkscape, ensuring decades-old documents remain viewable.
Initial release: 1988
PLT is a vector file format associated with HP-GL (Hewlett-Packard Graphics Language), a plotter control language introduced by Hewlett-Packard in 1977 with the HP-9872 pen plotter. PLT files contain a sequence of two-letter ASCII commands that instruct a pen plotter to move, draw lines, select pens, and render text — commands like PU (pen up), PD (pen down), PA (plot absolute), and SP (select pen) form a straightforward instruction set that directly controls physical drawing motion. The language operates on a coordinate grid measured in plotter units (typically 0.025 mm per unit), and the resulting files read almost like machine code for a drawing device. HP-GL became the dominant standard for computer-aided design output, adopted by virtually every CAD application and supported by plotters from all manufacturers throughout the 1980s and 1990s. One advantage is universal CAD compatibility — PLT files generated by AutoCAD, SolidWorks, or any engineering software can be sent directly to plotters and cutting machines without driver translation. The text-based, human-readable command structure is another strength: engineers can inspect, edit, and hand-write PLT files to troubleshoot output or generate simple drawings programmatically. HP-GL/2, an enhanced version introduced with the HP LaserJet III in 1990, added polygon fills, Bezier curves, and raster support. PLT remains actively used in engineering, architecture, and manufacturing for large-format output.

Frequently Asked Questions

Why convert WPG to PLT?

WPG is tied to WordPerfect — converting to PLT frees your graphics for use in any application, from web publishing to image editing.

What programs open PLT files?

AutoCAD, CorelDRAW, and HP plotter software. Used for large-format printing and CNC cutting machines.

Are my files secure during conversion?

All file transfers use encrypted connections. Uploaded WPG files are deleted after processing, and PLT outputs are purged within 24 hours.

Will the image quality change?

Image data is transferred faithfully from WPG to PLT. The conversion itself does not degrade or enhance the original pixel information.

Can I convert multiple WPG files at once?

Yes — Convertio supports batch uploads. Queue several WPG files and convert them all to PLT in one session, saving time on repetitive tasks.

What platforms are supported?

Any device with a web browser — Windows, macOS, Linux, iOS, Android, and Chrome OS. No software installation is needed for the conversion.
