Custom typography has become an essential part of modern web design. Whether you're building a personal blog, a business website, an online store or a web application, using the right font helps establish your brand while improving readability and user experience.
Desktop fonts are typically supplied as TrueType (TTF) or OpenType (OTF) files. Although browsers can load these formats directly, they were never designed specifically for the web. Modern websites instead use WOFF and WOFF2, compressed font formats created to reduce download sizes and improve loading performance.
This free online converter transforms TTF and OTF fonts into web-ready WOFF or WOFF2 files within seconds. Simply upload your font, choose the desired output format and download a compressed webfont that's ready to deploy on your website.
TrueType (TTF) is one of the most widely supported font formats ever created. Originally developed by Apple and Microsoft, it has become the standard desktop font format across Windows, macOS and Linux. TTF fonts are commonly used in word processors, graphics software and operating systems because they provide excellent compatibility and reliable rendering.
OpenType (OTF) builds on the TrueType format by introducing advanced typographic capabilities such as ligatures, alternate characters, small capitals, contextual substitutions and extensive multilingual support. Many professional typefaces are now distributed as OpenType fonts because of these additional features.
While both formats work well on desktop computers, websites generally benefit from converting them into dedicated webfont formats.
WOFF, which stands for Web Open Font Format, was specifically designed for serving fonts on websites.
Rather than transmitting the original desktop font, WOFF packages the font using lossless compression while preserving its glyphs, metadata and typographic information. The result is a significantly smaller file that downloads more quickly without affecting visual quality.
Benefits include:
For almost every modern website, WOFF is preferable to serving raw TTF or OTF files.
WOFF2 is the latest evolution of the Web Open Font Format.
Using Google's Brotli compression algorithm together with font-specific optimisations, WOFF2 files are often 20–40% smaller than equivalent WOFF fonts. The reduced size helps improve page speed, especially on mobile networks, while lowering bandwidth consumption for busy websites.
Most modern browsers fully support WOFF2, making it the preferred format for new projects. Many developers still provide a WOFF version as a fallback for older browsers, ensuring maximum compatibility.
This converter allows you to generate either format depending on your deployment requirements.
The conversion process begins by analysing the uploaded TrueType or OpenType font. The original font tables are preserved, and the font is repackaged into either WOFF or WOFF2 using the appropriate compression method.
When generating WOFF files, the font tables are individually compressed where beneficial. For WOFF2 output, the font data is compressed using Brotli to achieve even smaller file sizes while maintaining compatibility with modern browsers.
The resulting webfont retains the appearance and functionality of the original desktop font but is optimised for efficient delivery over HTTP.
Web fonts allow every visitor to see the same typography regardless of which fonts are installed on their computer.
They are commonly used for:
By self-hosting your fonts, you also gain greater control over caching, privacy and website performance.
For most new websites, WOFF2 is the recommended choice because it provides the highest compression and is supported by all major modern browsers.
WOFF remains useful when compatibility with older browsers is important. Many production websites serve both formats using CSS, allowing each browser to automatically download the best version it supports.
If you're unsure which to choose, WOFF2 is generally the best option for new development.
Although converting a font is technically straightforward, it's important to understand that font software remains protected by copyright and licensing terms.
Many commercial fonts include separate licences for desktop use and web embedding. Before publishing converted fonts on a website, always check that your licence permits web use.
This converter simply changes the file format—it does not alter ownership or licensing rights.
Yes. You can convert TTF and OTF fonts into WOFF or WOFF2 without registration or installation.
The converter accepts both TrueType (.ttf) and OpenType (.otf) font files.
You can generate either WOFF or WOFF2 depending on your needs.
WOFF2 usually provides the smallest file size and is recommended for modern websites. WOFF remains useful for legacy browser compatibility.
Yes. Multiple TTF and OTF files can be uploaded and converted during a single session.
No. The conversion uses lossless compression, so the visual appearance and glyph outlines remain unchanged.
No. Everything happens directly in your browser using the online converter.
Whether you're building a new website, improving an existing one or preparing fonts for production deployment, converting desktop fonts into WOFF or WOFF2 is one of the easiest ways to improve performance.
Upload your TrueType or OpenType fonts, choose your preferred output format and download compressed webfonts that are ready to use in modern browsers within seconds.
