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.

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.

Frequently Asked Questions

Why convert TTF to FAX?

FAX format produces images optimized for fax transmission — useful when you need to send font specimens or text renders through traditional fax systems.

What systems handle FAX images?

Fax machines, fax server software (HylaFAX, RightFax), and general image tools like ImageMagick and GIMP can handle fax-format images.

Is FAX a color format?

No. Fax images are black-and-white bitmaps, which actually works well for rendering clean font glyphs without unnecessary color data.

Can I convert multiple fonts at once?

Yes — Convertio supports batch uploads. Queue several TTF fonts and get individual FAX images for each in one session.

Is the conversion free?

Entirely free. Convertio handles TTF to FAX conversion with no payment or sign-up required.
