Minimal File Size

WBMP produces the smallest possible image files — 1-bit monochrome encoding makes them perfect for ultra-low-bandwidth delivery.

Legacy Mobile Support

WBMP was designed for WAP and feature phones. Convert your GIF to reach devices that cannot handle modern image formats.

Cloud Processing

Convertio handles the conversion on its servers — no special tools needed on your device. Upload and download through any browser.

About formats

GIF (Graphics Interchange Format) was introduced by CompuServe on June 15, 1987 as a platform-independent image format for transmitting color graphics over the CompuServe online service's modem-speed connections. The format uses LZW (Lempel-Ziv-Welch) lossless compression on indexed-color images with a palette of up to 256 colors selected from a 24-bit RGB color space. GIF's most distinctive capability is animation: multiple image frames can be stored sequentially within a single file, each with independent delay timing, disposal methods, and local color palettes, enabling short looping animations without any video codec or player. The format also supports binary transparency (one palette entry designated as fully transparent) and interlaced display for progressive rendering. GIF became synonymous with web culture — animated GIFs proliferated across early websites, messaging platforms, and social media, evolving into a communication medium in their own right. One advantage is universal animation support — GIF animations play natively in every web browser, email client, messaging app, and social platform without plugins, codecs, or compatibility concerns, a level of ubiquity no other animation format has achieved. The lossless compression on palette-based images provides another strength: graphics with flat colors, text, and sharp edges (logos, diagrams, UI elements) compress efficiently without the artifacts that affect JPEG. Although the LZW patents that once threatened GIF's use expired in 2004, and newer formats like WebP and AVIF offer superior compression with full-color animation, GIF's cultural entrenchment keeps it irreplaceable for casual animated content.

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 GIF to WBMP?

WBMP is a monochrome bitmap format for WAP devices — converting produces ultra-lightweight images for feature phones and low-bandwidth mobile scenarios.

What displays WBMP files?

WAP-enabled mobile browsers, some legacy phones, and image viewers like IrfanView and XnView can open WBMP files for viewing and editing.

Is WBMP only black and white?

Yes — WBMP stores 1-bit images (black and white only). Color information from the GIF is reduced to a monochrome threshold during conversion.

When is WBMP useful today?

WBMP remains relevant for embedded systems, IoT displays, and legacy mobile applications where bandwidth and memory are severely limited.

Will the file be very small?

Extremely — 1-bit monochrome images produce tiny files, making WBMP ideal for constrained environments where every byte matters.
