About This Conversion
Everything you need to know about converting between these formats
OpenType Font
OpenType Font (OTF) is an extension of TrueType, offering advanced typographic features like ligatures and alternate glyphs. It supports more characters and is preferred for professional design work due to its superior font rendering capabilities.
PostScript Type 1
PostScript Type 1 Binary (PFB) is an Adobe font format used primarily for professional printing. It offers high-quality rendering and was the standard for desktop publishing before TrueType and OpenType became dominant.

Frequently Asked Questions
Common questions about converting OTF to PFB
1Why would I convert OTF to PFB (PostScript Type 1)?
Almost never. PFB is obsolete technology from the 1990s. Even for print, modern workflows use OTF or PDF embedding. Only convert if you have ancient RIP software that explicitly requires PostScript Type 1 and cannot be upgraded.
2Does converting OTF to PFB preserve PostScript outlines?
If your OTF uses PostScript (CFF) outlines, conversion to PFB is theoretically cleaner than from TTF. However, PFB is so limited compared to OTF that you lose far more than you gain. OpenType features, extended character sets, and modern font data are all stripped.
3Will I lose OpenType features?
Yes, completely. PostScript Type 1 (PFB) predates OpenType by decades. All advanced typography is lost: ligatures, stylistic sets, contextual alternates, small caps tables. You keep basic glyphs and kerning only.
4Does PFB work better for print than OTF?
No. Modern print workflows handle OTF perfectly and prefer it. PFB is obsolete – Adobe stopped developing PostScript Type 1 in 1999. Any print system that needs PFB is critically outdated and should be upgraded.
5Can I use PFB on modern operating systems?
Poorly or not at all. Windows 10+ and macOS 10.13+ have dropped or severely limited PFB support. The fonts won't install properly. Stick with OTF for desktop use – it works everywhere PFB worked and everywhere it didn't.
6Is PFB smaller than OTF?
Sometimes slightly, but meaninglessly. PFB may be 10-20% smaller due to simpler structure, but you lose massive functionality. For web, WOFF2 is 60-70% smaller than either. For desktop/print, file size is irrelevant.
7Should I archive fonts as PFB?
Not recommended. PFB is a legacy format. Archive as OTF instead – it's the modern standard with long-term support. Use current, standardized formats for archival to ensure future compatibility.
8Can PFB be used on websites?
No. No browser has ever supported PFB/PostScript Type 1 fonts. For web use, convert OTF to WOFF2 (best compression) or WOFF (broader compatibility). PFB is a legacy print format that has been superseded.

Troubleshooting Common Issues
Solutions to problems you might encounter
PFB doesn't install on modern systems
Windows 10+ and macOS 10.13+ have dropped PostScript Type 1 (PFB) support. The font won't install or will fail with errors. Modern systems require TTF/OTF. Converting OTF to PFB destroys compatibility. Keep OTF.
Lost all OpenType features
PFB (PostScript Type 1) predates OpenType. All modern features are stripped: ligatures, stylistic sets, contextual alternates, extended characters. If you need modern typography, keep OTF or convert to TTF, not obsolete PFB.
PostScript curves degraded
Even though PFB uses PostScript outlines, the PostScript Type 1 format is far more limited than OpenType CFF. You lose outline quality and features despite both using PostScript math. This is a format limitation.
Print software doesn't recognize PFB
Modern print workflows use TTF/OTF embedded in PDFs. PFB is obsolete even for print. If your print RIP requires PFB, the equipment is from the 1990s and should be upgraded. Use OTF or TTF in modern print systems.
This conversion shouldn't exist
You're right. OTF to PFB is a massive downgrade: modern to obsolete, full features to no features, universal compatibility to zero support. There's no valid modern use case. Keep OTF or convert to TTF for broader compatibility.
When NOT to Use PFB
Scenarios where you should keep OTF or choose a different format
Modern operating systems
Why not: Windows 10+/macOS 10.13+ dropped PFB supportUse instead: Keep OTF - works on all modern systems; PFB obsoleteOpenType features needed
Why not: PFB predates OpenType; strips all modern featuresUse instead: Keep OTF to preserve all features; PFB has noneCross-platform use
Why not: PFB barely works anywhere in 2024Use instead: Keep OTF for universal compatibility; PFB is deadAny use in 2024
Why not: Adobe stopped developing Type 1 in 1999 (25 years ago)Use instead: Never convert to PFB; obsolete for a quarter century
