Fonts

Fonts

List supported fonts, install TrueType fonts/collections for stamps and watermarks, and create font cheat sheets.

Command line

pdfcpu2 fonts list                       # built-in (14 core fonts) + installed user fonts
pdfcpu2 fonts install my-font.ttf        # .ttf and .ttc
pdfcpu2 fonts install a.ttf b.ttf c.ttf
pdfcpu2 fonts cheatsheet                 # cheat sheet PDFs for user fonts
pdfcpu2 fonts cheatsheet my-font.ttf     # specific font

Installed fonts become available to stamp / watermark / create by name (font: MyFont). Core fonts: Helvetica, Times, Courier (+ bold/italic variants), Symbol, ZapfDingbats — always available, never embedded.

CJK tip: stamp/watermark support script: names (Hans, Hant, Hira, Kana, Jpan, Hang, Kore) that render via CID system fonts without embedding large font files — see Stamp.
