How to Convert Files

PFB is a PostScript Type 1 font in binary form, a format Adobe formally ended in 2023. This page covers what it is and why it must be migrated.

Inside a PFB File

PFB is the binary form of a PostScript Type 1 font, the format that effectively created desktop publishing. Type 1 describes outlines with cubic Bezier curves and its own hinting system, and for years it was what professional typesetting ran on.

Its structure reflects a workflow that no longer exists. A Type 1 font is often split across companion files: PFB or PFA for the outlines, PFM or AFM for the metrics. The pieces travel together and a font is incomplete without them.

A Deliberately Ended Format

Adobe ended support for Type 1 fonts in its applications in 2023. This is not gradual obsolescence but a stated end of life: software that once defined the format now refuses to load it.

Converting PFB to OTF is the migration path, and it is a natural one because OpenType's CFF outlines are cubic, exactly like Type 1's. The curves carry over cleanly, the metrics come along, and the result works in software that will not open the original.

Origin and Evolution of PFB

PFB was introduced by Adobe in 1984 as a binary representation of the PostScript Type 1 font format. It addressed the need for a more efficient way to store and transmit font data, particularly for desktop publishing applications. The format allowed for the compact storage of font outlines using cubic Bezier curves, which improved rendering speed and fidelity in printed materials.

Over the years, PFB gained traction in the graphic design and publishing industries, becoming a standard for professional typesetting. Various software tools emerged to support PFB, facilitating its integration into workflows. However, with the decline of Type 1 font support and the rise of OpenType, PFB's relevance diminished, culminating in Adobe's official cessation of support in 2023.

Using PFB Effectively

Choose PFB when working with legacy systems or applications that specifically require PostScript Type 1 fonts. It is suitable for projects that demand compatibility with older desktop publishing software. However, be mindful that modern applications may not support PFB, making it essential to verify compatibility before use.

When converting to or from PFB, ensure that the font outlines are properly preserved. Use dedicated font conversion tools that handle PFB natively to avoid data loss. Pay attention to hinting and kerning settings, as these may not translate seamlessly across formats. Test the output in the target application to confirm visual fidelity.
