How the Font to Base64 & Web Formatter Works

Select a TTF, OTF, or WOFF font file and instantly generate CSS @font-face code with the font encoded as a Base64 data URI string. Great for single-file HTML prototypes and embedding icons.

Usage Example

Convert a small custom icon font into a CSS file you can drop into any project.

Frequently Asked Questions

Is Base64 font embedding good for performance?

Base64 strings increase CSS size but reduce HTTP requests. It is recommended for small UI icon fonts rather than large full-family text fonts.
