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.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.

Frequently Asked Questions

Why convert WPG to TCR?

WPG images are trapped in the WordPerfect world. Converting to TCR liberates them for use in modern editors, presentations, and web content.

What can I use to view TCR files?

Psion devices, Calibre e-book manager, and legacy PDA e-book readers.

Can I read the TCR on my e-reader?

Yes — download the TCR file and transfer it to your e-reader or reading app. Most modern e-readers support the TCR format natively.

Will the image quality change?

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

Are colors preserved during conversion?

Color data from the WPG file is mapped accurately into TCR. The conversion maintains the original color profile as closely as the target format allows.

Are my files secure during conversion?

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