Tips for Converting WOFF to WOFF2
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
Web Open Font Format has a known limitation: larger than WOFF2 which uses more efficient Brotli compression. Web Open Font Format 2 addresses this with a key advantage: best compression of any web font format, 30% smaller than WOFF. Converting from WOFF to WOFF2 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
Web Open Font Format is most commonly used for web font delivery via css @font-face rules, while Web Open Font Format 2 is the standard for primary web font format for modern websites. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where WOFF is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the WOFF2 output
Web Open Font Format 2 has its own limitation worth understanding before you commit: not suitable for desktop application font installation. After the conversion completes, open the WOFF2 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.
