About formats

DOC is the binary document format of Microsoft Word), the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.

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 DOC to WBMP?

WBMP is a monochrome bitmap for WAP-enabled devices — converting DOC to WBMP is useful for legacy mobile and embedded systems.

How do I view WBMP files?

WBMP files can be viewed in IrfanView, XnView, GIMP, and applications designed for WAP or mobile device content.

Is WBMP a color format?

No — WBMP is strictly monochrome (black and white). Document pages are dithered to one-bit representation during conversion.

Is DOC to WBMP free?

Free DOC to WBMP conversion is available on Convertio. Premium plans provide extended capacity for larger workloads.

Does it handle multi-page DOC files?

Each page of your DOC document becomes a separate WBMP image — all pages are converted in a single session.
