什么是 PFB？PostScript Type 1 二进制字体格式解释
Adobe 的 PostScript Type 1 轮廓字体的二进制容器。

What is it?
PFB, short for Printer Font Binary, is a binary file format created by Adobe Systems for storing PostScript Type 1 outline fonts. Type 1 fonts were introduced by Adobe as part of the PostScript page description language and came into wide use with the Apple LaserWriter in 1985.
A PFB file is a compact wrapper around the data that would otherwise appear in an ASCII PFA file. It is organized as a series of segments, each marked as ASCII text or binary, where the binary portions, including the encrypted charstring outlines, are stored as raw bytes rather than as hexadecimal text. This makes PFB files roughly half the size of equivalent PFA files. On Windows, a PFB is paired with a PFM metrics file.
Technical Specifications
Pros & Cons
Advantages
Storing the binary section as raw bytes makes a PFB about half the size of the equivalent ASCII PFA file.
Type 1 fonts use cubic Bezier curves and hinting for crisp rendering, especially in print.
As the foundation of professional PostScript printing, Type 1 fonts were a print and publishing standard for decades.
Long supported across major operating systems and PostScript devices.
Disadvantages
Adobe ended authoring and support for Type 1 fonts in its applications in January 2023, encouraging migration to OpenType.
Type 1 fonts typically hold far fewer glyphs than modern OpenType fonts and lack advanced typographic features.
On some platforms a font requires separate outline and metrics files, complicating management.
When to Use It
PFB is encountered mainly in legacy print and font-archival contexts.
遗留打印工作流程
Older professional publishing and prepress systems relied on PostScript Type 1 fonts in PFB form.
字体转换
PFB files are converted to OpenType or other modern formats to keep older typefaces usable.
数字保存
Archives retain PFB fonts to reproduce historical documents and designs accurately.
How to open a PFB file
PFB files, representing the PostScript Type 1 Binary Font Format, can be managed through various software categories, including professional tools, free/open-source options, browser-based solutions, and built-in operating system utilities. Professional software typically offers advanced features for font design and editing, making it suitable for graphic designers and typographers. Free and open-source tools cater to users who need basic functionality without financial investment, while browser-based solutions provide accessibility without installation. Built-in utilities may offer limited capabilities for quick viewing or conversion.
When selecting software for PFB files, key decision factors include feature fidelity, the distinction between editing and viewing capabilities, cost models, and platform compatibility. Users should consider whether they need to edit fonts or simply view them, as this will influence the choice of software. Export needs are also crucial, as some applications may only allow saving in specific formats, while others offer broader compatibility. In some cases, converting PFB files to more widely supported formats may be a better option for users not needing extensive editing features.
