Tips for Converting TTF to WOFF
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
TrueType Font has a known limitation: larger file sizes than WOFF/WOFF2 for web delivery. Web Open Font Format addresses this with a key advantage: significantly smaller file sizes than TTF/OTF for faster web page loading. Converting from TTF to WOFF is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
TrueType Font is most commonly used for desktop application and operating system fonts, while Web Open Font Format is the standard for web font delivery via css @font-face rules. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where TTF is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the WOFF output
Web Open Font Format has its own limitation worth understanding before you commit: larger than WOFF2 which uses more efficient Brotli compression. After the conversion completes, open the WOFF file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Check licensing before converting and deploying
Font licenses often restrict how and where a font can be used. A desktop font license may not permit web embedding, and converting a font to a web format without the appropriate license may violate the font's terms of use. Always verify your license covers the intended deployment method before converting.

Source Format
TrueType Font
font/ttfTTF (TrueType Font) is a font format developed jointly by Apple and Microsoft in the late 1980s, using quadratic Bezier curves to define glyph outlines. It supports font hinting instructions that optimize rendering at small sizes on screen, and includes tables for kerning, ligatures, and other typographic features. TTF remains one of the most widely used font formats across all operating systems.
Advantages
- Universal support across Windows, macOS, Linux, and mobile operating systems
- Excellent screen rendering with built-in hinting instructions
- Well-established format with decades of tooling and ecosystem support
Limitations
- Larger file sizes than WOFF/WOFF2 for web delivery
- Quadratic curves are less efficient than cubic curves used in OpenType/CFF
- Single-style per file (no font collections without TTC container)
Common Uses
- Desktop application and operating system fonts
- Print document and graphic design typography
- Web fonts where WOFF/WOFF2 alternatives are not available
Target Format
Web Open Font Format
font/woffWOFF (Web Open Font Format) is a web font format that wraps TrueType or OpenType font data with additional compression and metadata in a web-optimized container. It was developed by the W3C to provide a standardized, compressed font format specifically for web delivery. WOFF typically achieves 40% compression compared to raw TTF/OTF files.
Advantages
- Significantly smaller file sizes than TTF/OTF for faster web page loading
- Standardized by the W3C with universal browser support
- Includes metadata for licensing and font origin information
Limitations
- Larger than WOFF2 which uses more efficient Brotli compression
- Not intended for desktop application use
- Requires decompression overhead when loading fonts
Common Uses
- Web font delivery via CSS @font-face rules
- Self-hosted web typography on websites and web applications
- Font distribution through web font services
