Convert desktop TTF and OTF fonts to compressed WOFF2 and WOFF web formats bidirectionally using WebAssembly with live typography preview.
Choose a font you have permission to use and compare the converted font’s actual rendering, not just its extension.
Compare letter shapes, punctuation, and digits before deployment. Compression size depends on the font; do not assume a fixed percentage reduction.
The file’s internal font tables and outlines determine compatibility. Conversion does not repair missing glyphs, create new styles, or change the font’s embedding license.
The current tool offers WOFF2 and TTF output selections. Test the downloaded file in the application that will use it.
The Free Font Converter (TTF/OTF ↔ WOFF2) is a high-speed browser-based typography converter that transforms desktop font files into ultra-compressed modern web fonts and vice versa. Web Open Font Format 2 (WOFF2) represents the industry standard for modern web typography, utilizing Google Brotli compression to achieve up to 30% smaller file sizes than legacy WOFF and over 50% smaller sizes than raw TrueType (TTF) and OpenType (OTF) formats. Reducing font file weight accelerates First Contentful Paint (FCP) and prevents Cumulative Layout Shift (CLS) on modern websites.
Powered by WebAssembly (Wasm) compiled from Google wawoff2 C++ libraries, our engine executes bidirectional conversion entirely inside your local browser memory. Convert desktop fonts (.ttf, .otf) into web-ready .woff2 and .woff files, or decompress web fonts (.woff2) back into desktop-compatible TrueType (.ttf) files with zero quality degradation or glyph loss.
Test your converted typography before downloading using the interactive preview suite. Type custom test sentences, adjust preview font sizes and letter spacing, inspect font metadata headers (family, weight, version, copyright, and postscript name), and review compression ratio savings in real time.
Drag and drop your desktop font or web font into the converter. The tool parses font tables and metadata instantly.
Choose WOFF2 for modern web deployment, WOFF for legacy web support, or TTF to decompress web fonts for desktop design software.
Audition the font across headings and body text using the live typography sandbox with adjustable font sizes and weights.
Click Download Font to retrieve your compressed font file alongside ready-to-use @font-face CSS snippets for your website.
Utilizes Google wawoff2 compiled to WebAssembly for byte-for-byte lossless font table compression and decompression.
Converts desktop TTF and OTF files to WOFF2/WOFF, and decompresses WOFF2 files back into desktop-compatible TTF format.
Audition custom test copy, inspect character sets, adjust font sizes, and view real-time compression savings metrics.
Executes all font parsing and compression in local device memory, guaranteeing commercial and custom fonts remain strictly private.
WOFF2 employs Brotli compression to cut font file weight by up to 50% compared to raw TTF. Test glyph rendering across font sizes before deploying custom web typography.
Convert a supported font to WOFF2, then check the output’s glyphs and typography in the intended browser.
Compare supported input and output formats without assuming that conversion adds missing characters or changes licensing rights.
| Font Web Format | Compression Algorithm & Container | File Size Efficiency & Browser Compatibility |
|---|---|---|
| WOFF2 | Brotli compression + custom WOFF2 transforms | Smallest file size (30–50% smaller than TTF); 98.5%+ browser support |
| WOFF | Deflate (zlib) compressed OpenType tables | Moderate size; legacy fallback for older browsers (IE9+, Safari 5.1+) |
| TrueType (TTF) | Uncompressed quadratic Bézier curves | Large file size; universal desktop standard for Windows, macOS, Linux |
| OpenType (OTF) | Uncompressed cubic Bézier CFF outlines | High typography precision for print; convert to WOFF2 for web deployment |
| @font-face CSS | CSS3 Web Fonts standard syntax | Pre-configured format("woff2") font declarations ready for production |
WOFF2 (Web Open Font Format 2) is a W3C recommendation that applies Brotli compression algorithm to OpenType/TrueType font tables. It delivers 30% to 50% smaller file sizes than WOFF and TTF, reducing mobile data usage and accelerating render speeds.
Yes. WOFF2 is natively supported by over 98% of all global web browsers including modern versions of Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, and Opera.
No. WOFF2 uses strictly lossless compression. All glyph vector paths, kerning pairs, ligatures, and hinting instructions remain completely intact and visually identical to the original TrueType or OpenType source.
