What Is Font Conversion?

Font conversion is the process of transforming a font file from one format to another while preserving all typographic data. Fonts are distributed in different formats designed for different purposes — TrueType (TTF) and OpenType (OTF) are the standard formats for desktop operating systems, WOFF and WOFF2 (Web Open Font Format) are optimized for web delivery via the @font-face CSS rule, EOT (Embedded OpenType) targets legacy Internet Explorer, and SVG fonts were designed for older iOS versions.

Converting desktop fonts to web-optimized formats matters for performance. WOFF2 uses Brotli compression — developed by Google and standardized by the W3C — achieving 30–50% smaller file sizes than WOFF and up to 70% smaller than raw TTF or OTF files. Serving WOFF2 fonts directly improves Core Web Vitals metrics like Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) by reducing font download time and eliminating invisible-text flashes.

This tool performs lossless conversion between 8 font formats — TTF, OTF, WOFF, WOFF2, EOT, SVG, DFONT, and PFB — covering 56 distinct conversion paths. Every conversion preserves all glyph outlines, kerning pairs, ligatures, and OpenType features. All processing happens in server RAM with zero files stored to disk, so licensed and proprietary fonts remain private throughout the process.

What Users Say About Our Font Converter

Trusted by designers, developers, and typography professionals worldwide.

Finally a converter that actually works! I was trying to get our company font working on our new website and nothing was converting properly. Dropped my TTF files here, got WOFF2 in like 2 seconds. Done. Bookmark this site.

Jake Morrison

Freelance Developer

Had a client send me 40+ OTF files that needed to be web-ready by Monday morning. Uploaded them all at once, selected WOFF and WOFF2, hit convert. Even gave me the CSS code to copy-paste. Saved my weekend honestly.

Priya Sharma

Web Designer

Love that it doesn't store my files. I work with licensed fonts all day and most online converters sketch me out. This one processes everything in memory and deletes it immediately. Finally something I can trust with client assets.
