.PFB (Printer Font Binary File) - File Extension

What is a PFB File?

The PFB file extension is a binary-encoded file format used for Adobe Type 1 fonts on Windows operating systems.

It is closely related to the PFA (Printer Font ASCII) file format, but instead of being encoded in ASCII, the PFB file is stored in binary format.

To use a PFB file as an active font, it requires an associated PFM (Printer Font Metrics) file. Both the PFB and PFM files should be stored within the system Fonts folder.

How to Open a PFB File

To open a PFB file, you need compatible software that can handle Adobe Type 1 fonts. Here are some commonly used software options:

• Adobe Illustrator: Adobe Illustrator is a professional vector graphics editor that supports the PFB file format. You can open PFB files in Illustrator to access and use the associated Type 1 font.
• Adobe Photoshop: Adobe Photoshop, a popular image editing software, also supports PFB files. Although primarily used for images, Photoshop can recognize and utilize the Type 1 fonts stored in PFB format.
• Font Book (macOS) and Fonts (Windows): Both macOS and Windows operating systems provide built-in font management utilities. Font Book on macOS and Fonts on Windows allow you to install and activate PFB fonts by simply copying the PFB and PFM files into the designated system Fonts folder.

How to Convert a PFB File

Converting a PFB file to another font format or vice versa requires specialized font conversion tools. Here are a few options:

• FontForge: FontForge is a free and open-source font editor that supports a wide range of font formats. It allows you to convert PFB files to other popular font formats like TrueType (.ttf) or OpenType (.otf), as well as convert fonts from other formats to PFB.
