Does converting PFB to WOFF2 reduce quality?

No, converting PFB to WOFF2 does not reduce quality. WOFF2 uses lossless compression, meaning the font outlines, glyphs, and visual appearance remain identical to the original. Only the file size changes.

What file size reduction should I expect?

You can expect a file size reduction of 50-70% when converting PFB to WOFF2. For example, a 150KB POSTSCRIPT TYPE 1 file typically compresses to around 45-75KB as WOFF2 due to Brotli compression.

Do WOFF2 fonts work in all browsers?

WOFF2 works in all modern browsers: Chrome 36+, Firefox 62+, Safari 11.1+, and Edge (all versions). It's not supported in IE11 or older browsers.

Will my font's OpenType features work after conversion?

Yes, all OpenType features are preserved during conversion. This includes ligatures, kerning pairs, alternate glyphs, small caps, and other advanced typography features. The conversion process adapts the container format while preserving all font data.

Can I convert commercial/licensed fonts?

You can convert commercial fonts for testing purposes, but you must purchase the appropriate web font license before using them on a live website. Font licenses are format-specific – a desktop license for one format doesn't automatically grant web usage rights. Always check your license agreement or contact the foundry.

How is PFB different from WOFF2?

PostScript Type 1 (PFB) is a font format with specific use cases. Web Open Font Format 2 (WOFF2) is the most efficient web format with Brotli compression. Choose based on your target platform and requirements.

What's the best format for my use case?

For modern websites, use WOFF2 as your primary format. Provide WOFF as a fallback for older browsers. For desktop applications, consider TTF or OTF.

Can I convert variable fonts?

Yes, variable fonts can be converted between formats while preserving all variation axes and design space. The conversion maintains the font's interpolation capabilities. Ensure your target browsers support variable fonts (Chrome 62+, Firefox 62+, Safari 11+).

About This Conversion

Everything you need to know about converting between these formats

Source Format

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.

Target Format

Web Open Font Format 2

WOFF2 is an improved version of WOFF with better Brotli compression, resulting in 30% smaller file sizes than WOFF. It's the preferred format for modern web applications and provides faster page load times.

Frequently Asked Questions

Common questions about converting PFB to WOFF2

1Why convert PFB to WOFF2?

To modernize obsolete PostScript fonts for modern web use. PFB is 1990s print format unsupported on modern systems; WOFF2 is cutting-edge web format with best compression. This brings ancient fonts into 2024 with 60-70% file size reduction.

2What's the conversion workflow?

Typically: PFB → TTF (intermediate) → WOFF2. Most converters can't go directly PFB to WOFF2. The TTF step converts PostScript to TrueType, then WOFF2 compression is applied. Some tools automate this pipeline.

3Should I also create WOFF fallback?

Yes, for IE11 support. WOFF2 works in 95%+ of browsers but not IE11. Provide WOFF2 (primary) + WOFF (IE9-11 fallback). This covers 99.9% of users with optimal compression for modern browsers.

4How much smaller is WOFF2 than PFB?

WOFF2 is typically 60-70% smaller. A 100KB PFB → 100KB TTF → 30-40KB WOFF2. Brotli compression (WOFF2) is extremely efficient. This dramatically improves page load performance.

5Can I use WOFF2 in desktop applications?

No, WOFF2 is web-only. Keep the intermediate TTF file for desktop use. Maintain separate files: TTF (desktop on all platforms), WOFF2 (modern web), WOFF (IE9-11 fallback).

6Does WOFF2 preserve PostScript quality from PFB?

Yes, perfectly. PFB → TTF → WOFF2 conversion is mathematically lossless. PostScript curves convert to TrueType (lossless), then WOFF2 compresses (lossless). Visual quality is pixel-perfect identical to original PFB.

7Will converted WOFF2 work in all modern browsers?

Yes. WOFF2 works in Chrome 36+, Firefox 39+, Safari 10+, Edge 14+, and all mobile browsers from 2016+. This covers 95%+ of current traffic. Only IE11 and older browsers need WOFF fallback.

8What's the best format to modernize PFB files?

For desktop: PFB → TTF (universal platform support, full OpenType). For web: PFB → TTF → WOFF2 + WOFF (optimal compression, broad compatibility). This brings 1990s PostScript fonts into modern cross-platform use.

Troubleshooting Common Issues

Solutions to problems you might encounter

Requires TTF intermediate step

Workflow: PFB → TTF → WOFF2. Most tools need the intermediate step. First modernize PostScript to TrueType, then apply WOFF2 compression. This is normal. Some pipelines automate the multi-step conversion.

Should I provide WOFF fallback?

Yes, for IE11 support. After PFB → TTF → WOFF2, also create WOFF. Provide both: WOFF2 (modern browsers, 95%+), WOFF (IE9-11 fallback). This covers 99.9% of users with optimal performance.

PostScript curves converted to TrueType

For web fonts, this is fine. The conversion is mathematically lossless – visual quality is pixel-perfect identical. Modern browsers render TrueType curves excellently. Focus on web benefits: WOFF2 provides 60-70% compression.

PFB had minimal features

PostScript Type 1 predates OpenType. If you need modern typography features, add them in the intermediate TTF step using font editing software before converting to WOFF2. The original PFB had no advanced features.

Massive file size reduction

This is excellent! PFB is uncompressed; WOFF2 uses Brotli compression. Expect 60-70% reduction. This modernizes 1990s PostScript fonts for 2024 web use with excellent compression and broad browser support.

When NOT to Use WOFF2

Scenarios where you should keep PFB or choose a different format

Must support IE11
Why not: WOFF2 doesn't work in IE11; need WOFF fallback
Use instead: Create both WOFF2 + WOFF from PFB for full coverage
Desktop use needed
Why not: WOFF2 is web-only; can't use in applications
Use instead: Convert PFB to TTF (desktop) + WOFF2 (web) separately
Font editing required
Why not: WOFF2 is delivery format; need TTF source
Use instead: Convert PFB to TTF for editing, then to WOFF2 for web
