About formats

CDR is the native file format of CorelDRAW, a vector graphics editor developed by Corel Corporation and first released for Windows in January 1989. The format stores complex vector illustrations using a RIFF-based container structure (Resource Interchange File Format), organizing page content, object properties, color palettes, and metadata across multiple data chunks. CDR supports a comprehensive range of vector objects including Bezier curves, rectangles, ellipses, artistic text, paragraph text, powerclips, drop shadows, transparency lenses, contours, blends, envelopes, and multi-page document layouts. Each new major release of CorelDRAW introduces an updated CDR version, sometimes adding features that are not backward-compatible with older software versions. One notable advantage is rich feature density — CDR files can contain extremely complex artwork combining vector objects with embedded bitmap effects, multi-point color fills, and mesh fills, all within a single native document. The format's strong presence in certain professional niches is another practical strength: sign-making, screen printing, engraving, and vinyl cutting industries widely standardize on CDR as their primary working format, with direct output to cutting plotters and production equipment. While CorelDRAW originated as a Windows application and CDR remains most fully supported on that platform, import support exists in competing editors including Inkscape, Adobe Illustrator, and LibreOffice Draw.

WBMP (Wireless Bitmap) is a monochrome (1-bit, black and white) image format defined as part of the Wireless Application Protocol (WAP) specification, developed by the WAP Forum (later consolidated into the Open Mobile Alliance) around 1998. The format was designed for the extremely constrained mobile devices of the late 1990s and early 2000s — phones with small monochrome screens, minimal processing power, and narrow bandwidth GSM data connections. WBMP uses the simplest possible encoding: a type identifier byte (always 0 for the only defined type), width and height encoded as multi-byte integers using a variable-length scheme, and the raw pixel data where each bit represents one pixel (0 for white, 1 for black) packed eight per byte. There is no compression, no metadata, and no color — the format is purely a minimal container for delivering small monochrome graphics to WAP-era mobile browsers. One advantage was extreme efficiency on constrained devices — WBMP images could be decoded with virtually zero CPU overhead and minimal memory, critical on early mobile hardware running at single-digit megahertz clock speeds. The tiny file sizes are another strength: a typical WBMP icon occupied just a few hundred bytes, practical for transfer over 9.6 kbps GSM data channels. While the WAP ecosystem has been entirely superseded by modern mobile web browsers capable of rendering full-color JPEG, PNG, and WebP images, WBMP files remain encountered in archived mobile content from that transitional era.

Frequently Asked Questions

Why convert CDR to WBMP?

WBMP is a monochrome image format designed for mobile and WAP devices. Converting CDR creates ultra-lightweight graphics for constrained platforms.

What opens WBMP files?

Mobile browsers, image editors like GIMP, and WAP-enabled devices support WBMP. IrfanView and XnView also handle it.

Is WBMP always black and white?

Yes — WBMP is a 1-bit format. Your CDR artwork is converted to monochrome (black and white) in the output.

Is this conversion free?

Completely free. Premium options exist for high-volume or professional use cases.

How small are WBMP files?

Extremely small — the 1-bit monochrome format creates tiny files, perfect for bandwidth-limited scenarios.
