Free Font Converter — TTF, OTF, WOFF, WOFF2 & EOT Online

Need to convert a font file from one format to another for web hosting, email templates, or cross‑browser compatibility? Our free online font converter transforms font files between TTF, OTF, WOFF, WOFF2, and EOT formats — all processed directly inside your browser with zero server uploads. Whether you're converting a desktop TTF to a lightweight WOFF for faster web loading, generating an EOT fallback for legacy Internet Explorer support, or extracting a raw OTF from a compressed WOFF package, this tool handles it in seconds with no installs, no signups, and no file‑size limits.

Why Font Format Conversion Matters for Web Performance

Fonts are one of the most critical render‑blocking resources on any web page. Serving the right format directly impacts First Contentful Paint, Largest Contentful Paint, and overall Core Web Vitals. WOFF and WOFF2 use compression to deliver font data in fewer bytes, which means faster downloads and better user experience — especially on mobile networks. Google Fonts, Adobe Fonts, and every major CDN serve WOFF2 by default because it's roughly 30% smaller than WOFF and up to 50% smaller than raw TTF or OTF. If you're self‑hosting fonts, converting to WOFF/WOFF2 is one of the easiest performance wins you can make.

• •WOFF2 files are 30–50% smaller than TTF/OTF, reducing download time and bandwidth costs
• •Serving the correct format eliminates render‑blocking delays and invisible text flash (FOIT)
• •WOFF format provides broad browser support back to IE 9 while keeping file sizes compact
• •EOT format ensures legacy Internet Explorer 6–8 compatibility for enterprise and government sites
• •Self‑hosting converted fonts gives you full control over caching, preloading, and subsetting strategies
• •Proper font delivery is a direct signal in Google's Page Experience and Core Web Vitals ranking factors

Supported Font Formats & Use Cases

Each font format exists for a reason, and choosing the right one depends on where and how the font will be used. Here's a quick guide to help you decide which format to convert to:

• •TTF (TrueType Font) — The universal desktop format supported by all operating systems. Ideal for local design work, desktop publishing, and as a source file for further conversions.
• •OTF (OpenType Font) — An advanced format supporting CFF outlines and OpenType features like ligatures and alternates. Preferred by designers for its extended typographic capabilities.
• •WOFF (Web Open Font Format) — Compressed font format designed specifically for the web. Supported by all modern browsers and recommended for web projects targeting broad compatibility.
• •WOFF2 (Web Open Font Format 2.0) — The latest web font standard using Brotli compression for maximum file‑size reduction. The gold standard for modern web font delivery.
• •EOT (Embedded OpenType) — Microsoft's legacy format for Internet Explorer. Required only when supporting IE 6–8 in enterprise or government environments.

Built for Developers, Designers & Agencies

Whether you're a frontend developer optimizing a client's self‑hosted font stack, a designer preparing font packages for a brand guidelines kit, or an agency building sites that need legacy IE support alongside modern performance, this converter fits into your workflow seamlessly. Upload a font, pick your target format, and download the result — no command‑line tools, no Python scripts, no complex build pipelines. Everything runs in your browser, so your font files never leave your device. This is especially valuable for agencies handling client fonts under strict NDAs or licensing agreements where uploading to third‑party servers is not an option.

How It Works — Simple, Fast, Secure

The conversion process is straightforward: upload your font file, and the tool automatically detects the source format. Choose your target format from the available options, hit convert, and download the result. The tool parses the binary font tables, applies the appropriate compression or decompression (zlib for WOFF, header manipulation for EOT), and rebuilds the file in the target format — all using JavaScript running locally in your browser. Your font files are never transmitted to any server. For web developers, this means you can convert an entire font family in minutes without installing command‑line utilities like woff2_compress, ttx, or fonttools.
