About This Conversion
Everything you need to know about converting between these formats
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.
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.
Why Convert PFB to OTF?
Professional design work requiring advanced typography
Accessing extended character sets and ligatures
Desktop publishing with sophisticated font features
Creating high-quality print materials

Frequently Asked Questions
Common questions about converting PFB to OTF
1Should I convert PFB to OTF or TTF?
Usually TTF unless you specifically need OTF. PFB uses PostScript curves, which can map to OTF (CFF) or TTF. However, TTF is more compatible and widely supported. Only choose OTF if you specifically need PostScript outlines preserved.
2Does OTF preserve PostScript curves from PFB better?
Yes, technically. OTF can use CFF (PostScript) outlines, maintaining the original curve format from PFB. However, for practical use, TTF conversion works equally well. The visual result is identical; only the mathematics differ.
3Will the converted OTF work on all platforms?
Yes. OTF has broad support, but TTF has even broader compatibility, especially with older software. For maximum compatibility from PFB, convert to TTF. Only use OTF if you specifically need to preserve PostScript outlines.
4Can I add OpenType features after converting PFB to OTF?
Yes! That's a major benefit. PFB has no OpenType features; OTF supports them fully. After conversion, use font editing software to add ligatures, stylistic sets, and modern typography that PFB could never support.
5Is OTF better for print than TTF from PFB?
No. Modern print workflows handle both equally well. The curve format (PostScript vs TrueType) doesn't affect print quality. Choose based on compatibility needs: TTF for maximum compatibility, OTF if preserving PostScript outlines matters.
6Can I use converted OTF on websites?
Don't use OTF directly on websites. After PFB → OTF conversion, convert to WOFF2 for web use. Or: PFB → TTF → WOFF2. This provides optimal compression and modern browser support.
7Does OTF preserve quality better than TTF from PFB?
Quality is identical. Both conversions are lossless. OTF preserves PostScript curve format; TTF converts to TrueType. Visual output is pixel-perfect identical either way. Choose based on compatibility needs, not quality.
8What's the best format to modernize PFB files?
For maximum compatibility: PFB → TTF. For preserving PostScript outlines: PFB → OTF. For web: PFB → TTF → WOFF2. Most users should choose TTF – it works everywhere and supports full OpenType features.

Troubleshooting Common Issues
Solutions to problems you might encounter
Should I preserve PostScript curves?
If using OTF with CFF (PostScript) outlines, yes, curves are preserved. However, many converters create TrueType-based OTF. For modernizing PFB, TTF is usually sufficient. Only use PostScript OTF if you specifically need to maintain curve format.
File size increased
OTF has more overhead than TTF or PFB. For general modernization of PFB files, TTF is often better: 10-30% smaller than OTF with identical functionality. Only choose OTF if you need to preserve PostScript outlines or client requires it.
PFB had minimal features
PostScript Type 1 predates OpenType. Basic glyphs and kerning are preserved, but advanced features didn't exist. After converting to OTF, you can add ligatures, stylistic sets, and other OpenType features using font editing software.
Why OTF instead of TTF?
Usually TTF is better for PFB modernization: smaller, more compatible. Only choose OTF if: (1) You want to preserve PostScript curves (CFF), (2) Client specifically requires OTF, or (3) You need features only available in OTF (rare).
Hinting needs to be recreated
PostScript Type 1 hints don't translate to OpenType. You'll need to re-hint the font using font editing software. For PostScript-flavored OTF, use PS hinting; for TrueType-flavored OTF, use TT hinting.
When NOT to Use OTF
Scenarios where you should keep PFB or choose a different format
File size matters
Why not: OTF is 20-25% larger than TTF from PFBUse instead: Convert PFB to TTF instead of OTF (smaller, more compatible)Maximum compatibility
Why not: TTF has broader support than OTF in older systemsUse instead: Convert to TTF instead of OTF from PFB sourcesArchival purposes
Why not: If maintaining historical PostScript collectionsUse instead: Keep PFB archived; convert to TTF (not OTF) for use
