Printer Font Binary for Image (.pfb)
The PFB (Printer Font Binary) file extension refers to an Adobe Type 1 font used primarily on Windows PCs. Developed by Adobe Systems, PFB files contain fonts in binary format, requiring an associated PFM (Printer Font Metrics) file for proper functionality. Initially proprietary, Adobe later released the specification to third-party font manufacturers. PFB files can also be converted to image files, and AutoCAD utilizes them to create compiled font files.
