Printer Font ASCII for Image (.pfa)
The PFA (Printer Font ASCII) file extension, developed by Adobe Systems, stores Adobe Type 1 fonts in a human-readable ASCII format, which can be converted to image files. Introduced as part of the PostScript character category in 1982, PFA files contain glyph data and can be opened in any text editor. They are primarily used on Linux and UNIX-like platforms and are incorporated into systems by copying them into the Fonts folder. The binary counterpart of PFA is the PFB (Printer Font Binary) file.
