About formats

TTF (TrueType Font) is a scalable outline font format developed by Apple Computer in the late 1980s and first shipped with Mac System 7 on May 13, 1991. Microsoft licensed the technology shortly after and included TrueType support in Windows 3.1 in 1992, establishing it as the dominant desktop font technology for over a decade. TrueType describes glyph shapes using quadratic Bezier splines — simpler mathematically than the cubic Bezier curves in PostScript fonts — stored alongside a powerful instruction set (the "hinting" language) that controls exactly how outlines are rasterized at each pixel size. This instruction-based hinting gives type designers pixel-level control over rendering at small sizes on low-resolution screens, producing exceptionally crisp text. The format stores all font data — outlines, metrics, kerning, naming, and hinting — in a single file organized as a directory of tagged data tables. One advantage is universal platform support: TTF files render natively on Windows, macOS, Linux, iOS, Android, and virtually every operating system and web browser without conversion or plugins. The byte-code hinting system is another distinctive strength, enabling screen rendering quality that remained superior to competing technologies until high-DPI displays reduced the importance of pixel-level optimization. TrueType's table-based architecture also proved remarkably extensible, serving as the structural foundation for the OpenType specification that added advanced typographic features and PostScript outline support on top of the TrueType container.

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 TTF to WBMP?

WBMP is the image standard for WAP mobile content — converting TTF to WBMP creates ultra-lightweight glyph renders for bandwidth-limited mobile devices.

What displays WBMP images?

WAP browsers on feature phones, mobile content management systems, and certain embedded displays support the WBMP format.

Is WBMP a color format?

No. WBMP is strictly 1-bit (black and white), making it extremely compact — ideal for simple text or icon renders on low-bandwidth connections.

Can I convert several fonts to WBMP?

Yes. Convertio allows batch uploads — add multiple TTF fonts and receive individual WBMP images for each.

Is there a cost for this?

TTF to WBMP conversion is completely free on Convertio — no account needed, no fees.
