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.

T11 (Type 11) is a PostScript font type defined by Adobe Systems as part of the CID-keyed font architecture, combining CID glyph addressing with TrueType outline data wrapped in a Type 42 PostScript shell. In Adobe's font type numbering, Types 9, 10, and 11 are CID-keyed counterparts to Types 1, 3, and 42 respectively — so Type 11 is essentially a CID-keyed Type 42, designed for TrueType fonts that contain very large glyph sets, particularly CJK (Chinese, Japanese, Korean) character collections. The format allows PostScript interpreters with TrueType rasterizer support to render CJK TrueType fonts while using CID numeric indexing instead of glyph names, which is critical for character sets numbering in the tens of thousands. Glyph outlines remain in native TrueType quadratic spline format, preserving the original hinting instructions, while the CID layer provides efficient glyph access and subsetting through CMap resources. One advantage is direct TrueType rendering quality — unlike converting TrueType outlines to PostScript cubics, Type 11 passes the original outlines to the rasterizer intact, preserving hand-tuned grid-fitting instructions. The CID indexing provides another benefit by supporting multiple encoding schemes (Unicode, national standards) mapped to the same glyph collection without data duplication. Type 11 fonts appear primarily in professional CJK print production and PDF document workflows where large TrueType-based character sets must be embedded in PostScript-derived output.

Frequently Asked Questions

Why convert TTF to T11?

T11 makes your TrueType fonts usable in TeX/LaTeX typesetting systems, which traditionally require Type 1 or CID-keyed fonts for proper rendering.

What systems use T11 fonts?

TeX, LaTeX, and related typesetting engines like pdfTeX and XeTeX use T11 font data. Academic publishing and scientific papers commonly rely on these systems.

Does the conversion keep all glyphs?

Yes, the full glyph set from your TTF is preserved in the T11 output, including special characters and extended Unicode ranges.

Is T11 the same as standard Type 1?

T11 is closely related to Type 1 but structured for TeX integration, with CID-keyed addressing that handles larger character sets.

Is there a cost to convert TTF to T11?

Convertio provides this conversion completely free — no payment, no registration, no limits on the number of conversions.
