The Font Base64 Encoder tool allows you to convert font files to base64 css @font-face quickly and securely. Like all SAMAST utilities, it runs entirely in your browser. This means your data is never uploaded to any external servers, ensuring complete privacy and fast execution.
Drag & drop or click to select files
100% local: Files never leave your device
Upload a font file to generate the CSS.
Note: Base64 encoding increases file size by ~33%. It's best used for small, highly-optimized font subsets (like WOFF2) or crucial icon fonts. Do not encode multiple large font files as it will block rendering while the CSS downloads.
