About formats

CMX (Corel Presentation Exchange) is a vector graphics exchange format developed by Corel Corporation, introduced with CorelDRAW 5 in September 1994. Designed as a cross-application interchange format within the Corel product suite, CMX stores vector objects, text, bitmaps, and rendering attributes in a structure accessible to CorelDRAW, Corel PHOTO-PAINT, Corel Presentations, and other Corel applications without requiring each program to understand the full CDR native format. The format uses a chunk-based architecture that encodes geometric primitives, fill patterns, outline properties, and color definitions in a standardized way, supporting both 16-bit and 32-bit variants. CMX gained significance beyond the Corel ecosystem through its adoption by third-party applications and its role in clipart distribution — many vector art collections from the mid-to-late 1990s shipped in CMX format. One advantage is interoperability within design workflows: CMX provided a practical bridge for moving vector content between different Corel applications while preserving visual fidelity, gradients, and transparency attributes. The format's inclusion of both vector and bitmap data within a single file is another strength, allowing complex mixed-media illustrations to be exchanged as self-contained units. Microsoft also added CMX import support to some Office applications, expanding the format's reach. While modern Corel applications primarily use CDR for native work and export to SVG, PDF, or EPS for interchange, CMX files from the CorelDRAW era remain widely encountered in legacy asset libraries.

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 CMX to WBMP?

WBMP is a monochrome format designed for mobile and low-bandwidth devices. Converting CMX to WBMP produces ultra-lightweight images for WAP pages.

What opens WBMP files?

IrfanView, XnView, GIMP, and most mobile WAP browsers display WBMP. It is commonly used in legacy mobile applications.

Is WBMP only black and white?

Yes — WBMP supports only 1-bit monochrome images. Your CMX design is rendered in black and white during conversion.

Is the conversion instant?

WBMP files are tiny, so conversion typically completes in a matter of seconds on Convertio cloud servers.

Can I convert from any device?

Absolutely — Convertio works in any web browser on desktop and mobile. No software installation required.
