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.

SK1 is the native file format of the sK1 project), an open-source vector graphics editor and conversion engine started by Igor Novikov in 2003 as a successor to Bernhard Herzog's Skencil. The format evolved from the original SK format, extending its capabilities while maintaining the text-based, Python-readable syntax for describing vector documents. SK1 files encode complete document structures including multiple pages, layers, guidelines, and a full hierarchy of graphic objects — Bezier paths, rectangles, circles, polygons, text blocks, and embedded raster images — with attributes for fills (solid, gradient, pattern, hatching), strokes, and transformations. The sK1 project distinguished itself by focusing on prepress and professional print production features, adding CMYK color management, ICC color profiles, spot color support, and PDF/PostScript output — capabilities unusual in open-source vector editors. One advantage is professional color handling — sK1's CMYK workflows and color management make it one of the few open-source tools suitable for print-ready vector production. The project's companion tool, UniConvertor, leverages the SK1 format as an intermediate representation for converting between numerous vector formats (CDR, CMX, WMF, EMF, SVG, and others), giving SK1 significance beyond the editor itself as a universal interchange format. The text-based file structure preserves the readability and scriptability advantages inherited from Skencil's original SK format.

Frequently Asked Questions

Why convert WPG to SK1?

WPG images are trapped in the WordPerfect world. Converting to SK1 liberates them for use in modern editors, presentations, and web content.

What software opens SK1?

sK1 vector editor, Inkscape (import), and UniConvertor for vector format conversion.

Do I need to install anything?

No — the entire conversion runs in your web browser. There is nothing to download or install on your computer or phone to convert WPG to SK1.

Is it safe to upload WPG files?

Convertio deletes uploaded files immediately after conversion. Converted output is removed from servers within 24 hours for your privacy.

Will I get scalable vector output?

The converter traces the raster WPG data into SK1 vector format. Results depend on image complexity — simpler graphics vectorize best.

Where can I upload WPG files from?

You can upload from your local device, Google Drive, Dropbox, or paste a direct URL. Convertio pulls the WPG file from any of these sources.
