PFB to UFO conversion is the process of transforming a font file in PostScript Printer Font Binary (PFB) format into the Unified Font Object (UFO) format used for editable, source-level font design. This conversion extracts glyph outlines, metrics, kerning and font metadata from the binary PFB and stores them in the structured, human-readable UFO package suitable for modern font editors and version control.

PFB files typically have the MIME type 'application/x-font-type1' and are used for PostScript font storage. UFO files use a directory structure with XML files describing font data, supported by many font editors. The conversion process handles glyph outlines and font metadata to ensure compatibility between these different codecs.
The UFO (.UFO) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like PFB.

PFB files are binary font files primarily used for PostScript Type 1 fonts, often limited in editing flexibility. UFO is an open, XML-based font format designed for modern font development, offering better readability and ease of modification. Converting PFB to UFO enables more efficient font editing and integration with contemporary design tools.
Keep source PFB files below 100–200MB for smooth browser-based conversion; larger files are better handled by desktop tools.
To preserve quality, avoid aggressive automatic curve simplification; choose a conversion path that retains original PostScript cubic outlines when possible.
For batch conversion, process PFB files in smaller groups (10–50 files) to reduce memory spikes and verify output integrity regularly.
Be aware that some PFB files may be subsetted or encrypted; such files can lose glyphs or metadata during conversion and may require the original source or license to fully recover.
