Understanding Font Formats
Font formats have evolved significantly over the decades, from simple bitmap fonts to sophisticated vector outlines with advanced typographic features. Each format was designed to solve specific problems in typography, printing, or digital display.
TrueType (TTF) and OpenType (OTF) are the most common formats today, offering broad compatibility across all platforms and devices. For web use, WOFF and WOFF2 provide excellent compression while maintaining quality and are supported by all modern browsers.
PostScript fonts like PFA, PFB, and CFF were the professional standard for printing for many years and are still used in publishing workflows. Legacy formats like DFONT and SUIT are specific to older operating systems but may still be needed for compatibility with vintage software.
Understanding these formats helps you choose the right one for your project. For maximum compatibility, TTF is recommended. For web performance, WOFF2 is best. For professional printing, PostScript formats or OTF with CFF outlines are preferred.
Frequently Asked Questions
What's the difference between TTF and OTF?
TTF (TrueType) uses quadratic Bézier curves, while OTF (OpenType) can use either TrueType or PostScript (cubic Bézier) outlines. OTF supports more advanced typography features like ligatures and contextual alternates.
Should I use WOFF or WOFF2 for my website?
Use WOFF2 as your primary format—it offers 30-50% better compression than WOFF and is supported by all modern browsers. Include WOFF as a fallback for older browsers if needed.
Can I convert any font format to any other format?
Most conversions are supported, but some combinations aren't possible. For example, metrics-only formats (AFM, PFM, TFM, BIN) don't contain glyph outlines and can't be converted to outline formats. Check each format's page for specific conversion capabilities.
Are PostScript fonts still relevant?
PostScript fonts are still used in professional printing and publishing. However, for most modern uses, OpenType (OTF) fonts with PostScript outlines are preferred as they offer better features and compatibility.
What is UFO format used for?
UFO (Unified Font Object) is a source format for font design and development. It's XML-based and human-readable, making it ideal for version control and collaboration between font designers using different tools.
