TrueType (TTF) fonts work great on desktops but are uncompressed and unnecessarily large for web pages. WOFF wraps the same font data with zlib compression, cutting file size by 30-40%. Use the MyPDF TTF to WOFF converter to prepare your TrueType fonts for the web.

How to Convert TTF to WOFF

  1. Upload — Drag your .ttf file into the converter or click to select it.
  2. Convert — The tool compresses the font and wraps it in the WOFF container format.
  3. Download — Save the .woff file and reference it in your stylesheet.

When to Use WOFF vs TTF

ScenarioRecommended Format
Web pages and web appsWOFF (or WOFF2)
Desktop applicationsTTF or OTF
Email newslettersWeb-safe system fonts
Electron / desktop web appsWOFF2 preferred
Legacy browser support (IE 9+)WOFF

Practical Tips

  • Generate WOFF2 as well. For the best performance, convert your TTF to both WOFF and WOFF2 and serve WOFF2 as the primary format.
  • Subset first for single-language sites. Use the Font Subset tool to keep only the character sets you need.
  • Preview before deploying. Check how the converted font renders at different sizes with the Font Preview tool.

Is the conversion lossless?

Yes. WOFF is a container format with compression — no glyph data, hinting, or kerning information is altered during conversion.

Can I convert a variable TTF font to WOFF?

Yes. The WOFF container supports variable font tables. All axes and named instances are preserved in the output file.

How do I use the WOFF file in CSS?

Add a @font-face block specifying the .woff file with format('woff'). Place WOFF2 before WOFF in the src list so browsers prefer the smaller format when supported.
