About formats

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.
Initial release: 2003
WMF (Windows Metafile) is a vector graphics format created by Microsoft, introduced with Windows 3.0 in May 1990 as the platform's native format for recording and replaying graphical operations. A WMF file captures a sequence of GDI (Graphics Device Interface) drawing commands — lines, rectangles, ellipses, polygons, text, and bitmap blits — in the order they were issued, serializing screen or printer output into a replayable file. The format uses a 16-bit coordinate space and organizes records as a linear stream of function calls with their parameters, preceded by a header specifying the bounding rectangle and resolution. WMF became deeply integrated into the Windows ecosystem as the default format for clip art collections, Office document graphics, and clipboard vector interchange during the 1990s — Microsoft Office shipped with thousands of WMF clip art images that defined a visual era of desktop publishing. One advantage is pervasive compatibility: virtually every Windows application from the past three decades can render WMF content, making it one of the most widely supported vector formats in existence. The lightweight recording model is another strength — WMF files are compact and render quickly because they replay native system drawing calls rather than interpreting a complex graphics language. While 16-bit limitations and lack of transparency and Bezier curves led Microsoft to develop EMF as a 32-bit replacement, WMF files remain ubiquitous in legacy documents and across current Windows software.

Frequently Asked Questions

Why convert SK1 to WMF?

WMF ensures broad compatibility with older Windows applications. Converting SK1 to WMF bridges the gap between Linux vector tools and Windows software.

How do I open WMF files?

WMF opens in Microsoft Word, PowerPoint, LibreOffice Draw, Inkscape, and most image viewers on Windows systems.

Is WMF a vector or raster format?

WMF is a vector metafile format. It preserves scalable geometry from your SK1 source, so graphics remain sharp at any size.

Does this conversion cost anything?

SK1 to WMF conversion is free on Convertio. Premium tiers provide expanded capacity for heavy or professional use.

Can I use WMF in older Office versions?

WMF has been supported since early Windows versions. It works in Office 2003, 2007, and all subsequent releases without issues.
