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.
Developer: WAP Forum
Initial release: 1998
RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

Why would I convert WBMP to RGB?

Few modern tools handle WBMP natively. RGB provides Silicon Graphics image format, making it widely recognized across operating systems and applications.

What programs open RGB files?

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

Is my WBMP file safe when converting online?

Convertio takes privacy seriously — your WBMP uploads are deleted after conversion and the RGB results are cleared within 24 hours.

What exactly is the WBMP format?

WBMP is a monochrome bitmap from the WAP era for early mobile phones. Originally from WAP mobile phones, it has become a legacy format — conversion is the most practical way to use these images today.

Does converting WBMP to RGB affect quality?

Quality is maintained to the extent RGB supports. Since WBMP is a monochrome bitmap from the WAP era for early mobile phones, the visual data transfers cleanly to RGB.

What platforms support this WBMP converter?

Since it runs in the browser, any operating system works — desktop or mobile. No platform-specific software is needed to convert WBMP to RGB.
