Source format: PFB
PFB stands for Printer Font Binary. It is a binary font file format used mainly for PostScript Type 1 fonts, especially on Windows and in older desktop publishing workflows. A PFB file usually stores the outline data for a Type 1 font, often paired with a .pfm metrics file. It was commonly used by graphic designers, publishers, and print-production systems that relied on PostScript-compatible fonts.
PFB files are mostly encountered in legacy font collections, archived design projects, and older operating systems or applications that still support Type 1 fonts.
Target format: WOFF
WOFF means Web Open Font Format. It is a web font container designed for use on websites and supported by modern browsers. WOFF packages font data in a compressed form, making it efficient for web delivery while preserving font metadata. It is widely used by web developers because it loads faster than many traditional desktop font formats and is easy to embed with CSS.
WOFF is especially useful for website typography, branding, and responsive design. It is a better fit than Type 1 fonts for web use because browsers do not natively use PFB files.
How to perform the conversion
The most practical way to convert PFB to WOFF is to use a font editor or font conversion tool that can open Type 1 fonts and export web fonts. A reliable desktop option is FontForge, which supports importing Type 1 fonts and exporting WOFF.
- Install FontForge on your computer.
- Open the
.pfbfile in FontForge. If the font has a matching.pfmfile, keep it in the same folder so metrics can be read correctly. - Check that the font opens properly and that the glyphs look correct.
- Use File → Generate Fonts or File → Export, depending on the version.
- Choose WOFF as the output format.
- Save the converted file with a
.woffextension. - Test the resulting font in a browser or web project by referencing it in CSS with
@font-face.
If you only need a quick conversion without installing software, you can convert the file on 101convert.com for free, directly in the browser.
Notes on quality, compatibility, or limitations
Type 1 fonts are legacy fonts, so conversion quality depends on how well the source PFB is structured and whether all required font data is present. If the font is damaged, missing metrics, or uses unusual Type 1 features, the converted WOFF may not render perfectly.
Also note that WOFF is intended for web use, not for general desktop installation. If you need broader browser compatibility, you may also want to generate .woff2 alongside .woff. Some older Type 1 fonts may have licensing restrictions that limit redistribution after conversion, so verify the font license before publishing it on a website.
