Best for web. ~30% smaller than WOFF. Supported by all modern browsers.
WOFF
Good web support including IE9+. Use as fallback alongside WOFF2.
TTF
Desktop apps & older systems. No web compression — use WOFF2 for websites.
OTF
Supports advanced typographic features (ligatures, alternates). Desktop use.
Why Convert Fonts to WOFF2?
Web fonts account for a significant portion of page weight on most sites. WOFF2, the Web Open Font Format version 2, uses Brotli compression to produce files roughly 30% smaller than WOFF and up to 50% smaller than raw TTF or OTF. Smaller font files load faster, reducing Largest Contentful Paint (LCP) and improving Core Web Vitals scores. Every major browser released in the last five years supports WOFF2, so there is no reason not to use it.
If you still need to support Internet Explorer 11 or very old mobile browsers, serve WOFF as a fallback alongside WOFF2 in your @font-face declaration.
Frequently Asked Questions
Why should I convert fonts to WOFF2?
WOFF2 uses Brotli compression which produces files roughly 30% smaller than WOFF and up to 50% smaller than raw TTF. Smaller font files mean faster page loads and better Core Web Vitals scores. WOFF2 is supported by all modern browsers.
What is the difference between TTF and OTF?
Both are desktop font formats. TTF (TrueType) uses quadratic Bezier curves and is the older standard. OTF (OpenType) is a superset that adds advanced typographic features like ligatures, swashes and extended character sets. For web use, both should be converted to WOFF2.
Is my font file kept private?
Your font file is sent to EazyStudio's conversion server to perform the format conversion, then immediately deleted. It is not stored, shared or analysed. The converted file is returned directly to your browser for download.
What is the maximum font file size?
There is no hard limit. Most web fonts are under 1 MB. If your font is very large it likely contains an extensive character set — consider subsetting it first (keeping only the characters you need) to reduce both upload size and the final converted file size.
