Frequently Asked Questions
Why convert TTF or OTF to WOFF2 for websites?
WOFF2 utilizes Brotli compression, resulting in 30-50% smaller file sizes compared to TTF, which dramatically boosts Core Web Vitals and page load speeds.
Are my commercial or licensed fonts kept private?
Yes! Unlike cloud converters, NEOKYRU processes the font binary completely in your browser memory. Your font files never touch our servers.
