Convert PFB to PT3

The PFB (Printer Font Binary) file extension is associated with Adobe's Type 1 fonts, primarily used in Windows operating systems. These files store font data in a compact binary format, which includes glyph data and encryption for protection. Introduced in the 1980s, PFB files were part of Adobe's PostScript technology, enabling high-quality digital typesetting. They work alongside PFM (Printer Font Metrics) files, which contain character measurements. PFB files are essential for precise font rendering in professional printing and digital design.

PostScript Type 3 (PT3) is a file format developed by Adobe Systems in the 1980s for font files in PostScript language. Unlike the more common PostScript Type 1 format, PT3 allows for the inclusion of complex graphics and color. However, it is less widely used due to its lack of support for hinting, which affects the clarity of text at small sizes. PT3 was largely replaced by Type 1 fonts and later OpenType formats. It served as an important step in the evolution of digital typography, allowing greater flexibility and creativity in font design.
