Does converting PFB to WOFF reduce quality?

No, converting PFB to WOFF does not reduce quality. WOFF 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 40-60% when converting PFB to WOFF. For example, a 150KB POSTSCRIPT TYPE 1 file typically compresses to around 60-90KB as WOFF due to gzip compression.

Do WOFF fonts work in all browsers?

WOFF fonts work in all modern browsers and most older ones. Support includes Chrome 36+, Firefox 39+, Safari 5.1+, Edge (all versions), and Internet Explorer 9+.

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 WOFF?

PostScript Type 1 (PFB) is a font format with specific use cases. Web Open Font Format (WOFF) is a web format with broad browser support. Choose based on your target platform and requirements.

What's the best format for my use case?

For modern websites, use WOFF 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

Web Open Font Format (WOFF) is specifically optimized for web use with built-in compression. It's supported by all modern browsers and is ideal for websites. WOFF files are typically 40% smaller than their TTF/OTF equivalents.

Why Convert PFB to WOFF?

Deploying fonts for web applications with broad browser support

Reducing font file sizes for improved website performance

Ensuring compatibility with browsers from IE9 onwards

Creating web font kits for responsive design projects

Frequently Asked Questions

Common questions about converting PFB to WOFF

1Why convert PFB to WOFF?

To use obsolete PostScript fonts on the web. PFB is print-only (and obsolete there); WOFF is for web. Better workflow: PFB → TTF → WOFF2 (modern) + WOFF (IE9-11 fallback). This provides optimal compression.

2Can I convert PFB directly to WOFF?

Most converters require: PFB → TTF → WOFF. PFB is a PostScript print format; WOFF is a web format. The TTF intermediate step ensures proper conversion from PostScript to TrueType outlines before web compression.

3Should I convert to WOFF or WOFF2?

WOFF2 for best results. After PFB → TTF conversion, create both WOFF2 (modern browsers, superior compression) and WOFF (IE9-11 fallback). This covers 99.9% of browsers with optimal performance.

4Will the converted WOFF work in all browsers?

WOFF works in IE9+, Chrome, Firefox, Safari, Edge, and all mobile browsers from 2015+. This covers 99%+ of traffic. For even better compression, also create WOFF2 (25-30% smaller than WOFF).

5Can I use WOFF in desktop applications?

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

6Does converting PFB to WOFF preserve PostScript quality?

Yes, losslessly. The conversion PFB → TTF converts PostScript to TrueType curves (mathematically lossless), then WOFF compresses it. Visual quality is pixel-perfect identical. Only the underlying mathematics change.

7How much smaller is WOFF than PFB?

WOFF is typically 30-50% smaller. PFB is already compact (binary encoding), but WOFF's gzip compression provides additional savings. For even better compression, use WOFF2 (60-70% smaller than PFB).

8What's the best workflow for PFB to web fonts?

PFB → TTF (conversion) → WOFF2 (modern web) + WOFF (IE9-11 fallback). This modernizes obsolete PostScript fonts for cross-browser web use with optimal compression. Discard PFB; keep TTF for desktop if needed.

Troubleshooting Common Issues

Solutions to problems you might encounter

Requires TTF/OTF intermediate step

Workflow: PFB → TTF → WOFF. Most tools can't convert PFB directly to WOFF. This is normal. First modernize the PostScript font to TTF/OTF, then compress to WOFF for web use. Some pipelines automate this.

PostScript curves converted to TrueType

For web fonts, this doesn't matter. The conversion is visually lossless. Modern browsers render TrueType curves perfectly. Focus on web benefits: WOFF provides 40-60% compression for fast page loads.

Should I use WOFF or WOFF2?

Use both! After PFB → TTF → WOFF/WOFF2 conversion, provide WOFF2 (modern browsers, best compression) + WOFF (IE9-11 fallback). This covers 99.9% of users with optimal performance.

PFB had no OpenType features

PostScript Type 1 predates OpenType. The converted WOFF has basic glyphs only. If you need modern typography, add OpenType features in the intermediate TTF step using font editing software before converting to WOFF.

File size reduction excellent

This is good! PFB is uncompressed; WOFF is compressed. Expect 40-60% reduction. This modernizes old PostScript fonts for modern web use. For even better compression, also create WOFF2 (60-70% reduction).

When NOT to Use WOFF

Scenarios where you should keep PFB or choose a different format

Better compression needed
Why not: WOFF2 is 25-30% smaller than WOFF
Use instead: Convert PFB to WOFF2 instead; use WOFF only as fallback
Modern web only
Why not: If you don't support IE11, WOFF2 is better
Use instead: Convert to WOFF2 from PFB; skip WOFF unless IE11 needed
Desktop use also needed
Why not: WOFF is web-only; can't use in desktop apps
Use instead: Convert PFB to TTF (desktop) + WOFF2 (web) separately
