Frequently Asked Questions

What is the difference between OTF and WOFF2?
OTF (OpenType Font) is a sophisticated font format with advanced typography features like ligatures and extensive character sets. WOFF2 is a web-optimized version that compresses OTF fonts by 30-50% while preserving all OpenType features, making them perfect for web use.
Will converting OTF to WOFF2 preserve OpenType features?
Yes, converting OTF to WOFF2 preserves all OpenType features including ligatures, kerning, alternate characters, and advanced typography features. WOFF2 is essentially a compressed container for the same font data, maintaining full functionality.
How much can I reduce OTF file sizes with WOFF2?
OTF fonts typically become 30-50% smaller when converted to WOFF2 due to advanced Brotli compression. With additional font subsetting (removing unused characters), you can achieve 80-95% size reduction while keeping only the characters you actually need.
Should I subset complex OTF fonts for web use?
Absolutely. OTF fonts often contain thousands of characters and multiple language sets. Subsetting removes unused characters while preserving the ones you need, dramatically reducing file size. Choose language-specific subsets or custom character sets based on your content.
Can I use OpenType features in web browsers with WOFF2?
Yes, modern browsers fully support OpenType features in WOFF2 fonts. You can enable ligatures, kerning, and other features using CSS properties like font-feature-settings, font-variant-ligatures, and other font-variant properties.
Are there licensing considerations for OTF fonts?
Yes, always verify your OTF font license before web use. Many commercial OTF fonts require separate web licenses. Some allow conversion for web use, while others restrict it. Open-source fonts like those from Google Fonts can be freely converted and used.
