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.

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.
