A Printer Font Binary (PFB) file is a type of font file used specifically in the context of Adobe Type 1 fonts. It stores font data in a binary format, which includes the glyph shapes and font metrics necessary for rendering text accurately on screens and in print. The PFB file is typically used in conjunction with a metric file (with an .AFM or .PFM extension) that provides additional layout information. This file format was widely used for high-quality typography on PostScript printers.
UFO3 (Unified Font Object 3) is a file type used for storing font data. It is a cross-platform, open source format that is used to store vector glyphs, font metrics, kerning data, and other related information. UFO3 is the most recent version of the UFO format, and is the standard for font interchange between applications.
