Convert TTF to CID

TTF, or TrueType Font, is a digital font standard developed by Apple in the late 1980s to ensure high-quality text display on screens and printers. It was later adopted by Microsoft, becoming widely used in both Mac and Windows operating systems. TTF files contain vector outlines for each character, allowing scalable text that maintains clarity at any size. Its major uses include web design, desktop publishing, and software development, where precise and consistent font rendering is critical. The TTF format revolutionized typography by providing cross-platform compatibility and superior control over font appearance.

The CID (Character Identifier) file extension, developed by Adobe, is used for CID-keyed fonts, which are composite (multibyte) Type 1 fonts designed to support large character sets, particularly for East Asian languages like Chinese, Japanese, and Korean. These fonts address glyphs by number rather than name, allowing for efficient handling of extensive character sets. Introduced to meet the demands of the Far East markets, CID fonts facilitate high-quality digital typesetting and printing by leveraging the PostScript language.
