About formats

CCX (Corel Compressed Exchange) is a compressed vector clipart format developed by Corel Corporation, introduced alongside CorelDRAW 5 in 1994. The format is essentially a compressed variant of CMX (Corel Presentation Exchange), packaging vector artwork, embedded bitmaps, and metadata into a smaller file suitable for distribution on CD-ROM clipart collections and online galleries. CCX files use the same underlying data structure as CMX but apply compression to reduce storage requirements — an important consideration during the 1990s when clip art libraries containing thousands of images shipped on capacity-limited media. Corel distributed vast collections of CCX clipart with CorelDRAW suites, and the format became synonymous with the extensive ready-made graphic libraries that distinguished Corel's product offerings. The artwork stored in CCX files ranges from simple geometric shapes to detailed illustrations, covering categories like business, nature, people, symbols, borders, and decorative elements. One advantage is compact storage — compression allows large clipart libraries to occupy significantly less disk space than equivalent uncompressed vector files. The ready-to-use nature of CCX content is another strength, providing designers with drag-and-drop artwork that scales cleanly to any size without quality loss, inheriting the resolution independence of the underlying vector data. While the format saw its peak usage during the CorelDRAW 5 through 12 era, CCX files remain openable in current versions of CorelDRAW and can be converted to modern 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.

Frequently Asked Questions

Why convert CCX to SK1?

CCX requires CorelDRAW. SK1 is an open vector format that works with the sK1 editor and the UniConvertor toolkit.

What application opens SK1 files?

The sK1 illustration program is the primary editor. UniConvertor can also read and process SK1 format natively.

Are vector details preserved?

Vector geometry transfers cleanly — curves, paths, and shapes remain editable in the SK1 output.

How quick is the conversion?

Most files convert in just seconds. Cloud infrastructure ensures the process is fast and independent of your hardware.

Is registration required?

No signup needed. Just upload your CCX file, select SK1, and download the result — completely open access.
