About formats

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.

PCX (PiCture eXchange) is a raster image format created by ZSoft Corporation in 1985 as the native format of their PC Paintbrush application, one of the first painting programs for IBM PC compatibles. The format uses a simple run-length encoding (RLE) compression scheme that works by replacing consecutive identical pixel values with a count-value pair, achieving modest compression on images with large areas of uniform color. A PCX file consists of a 128-byte header (specifying dimensions, color depth, palette information, DPI, and encoding method), the RLE-compressed pixel data organized in scan-line order, and an optional 256-color palette appended after the image data. The format evolved through several versions supporting increasing color depths: 1-bit monochrome, 4-bit (16 colors), 8-bit (256 colors), and 24-bit true color using multiple color planes. PCX became one of the most popular image formats during the DOS era, widely supported by paint programs, word processors, desktop publishers, and early games throughout the late 1980s and early 1990s. One advantage was broad DOS-era software compatibility — PCX served as a practical interchange format when competing programs used proprietary raster formats. The simplicity of RLE decoding is another strength, requiring minimal CPU and memory resources ideal for the hardware of that period. While PNG, JPEG, and other modern formats have replaced PCX in contemporary use, the format remains encountered in legacy archives and retro computing contexts.

Frequently Asked Questions

Why convert WBMP to PCX?

Few modern tools handle WBMP natively. PCX provides run-length encoded bitmap from early PC graphics, making it widely recognized across operating systems and applications.

What programs open PCX files?

Open PCX using IrfanView, XnView, GIMP, Photoshop. Cross-platform support means you can access these files on virtually any system.

Are my uploaded files kept private?

Yes — your WBMP files are deleted immediately after processing. The resulting PCX files are also removed from servers within 24 hours.

How long does WBMP to PCX conversion take?

Conversion is nearly instant for most WBMP files. Since these are small images, the entire process — upload to download — takes only moments.

Is WBMP to PCX conversion free?

You can convert WBMP to PCX for free on Convertio. Premium plans are available if you need higher throughput or larger file allowances.

Does this converter work on mobile devices?

The converter is browser-based and fully responsive. Convert WBMP to PCX from any device — desktop, laptop, tablet, or smartphone.
