How Can I Convert Web Fonts to Base64 While Preserving Their Original Appearance?

Preserving Originality in Web Font Base64 Conversions

Encoding web fonts to base64 offers deferred loading benefits. However, it's essential to address the concern that converted fonts may deviate from their original appearance.

Step-by-Step Base64 Conversion with Exact Rendering

To ensure identical font rendering after conversion, follow these steps:

1. Adjust TrueType Hinting: In Font Squirrel's Expert options for CSS conversion, set 'TrueType Hinting' to 'Keep Existing.' This preserves the font's original hints.
2. Retrieve Direct GWF File (Optional): If preferred, obtain the desired font directly from Google Web Fonts (GWF).

3. Encode to Base64:

   • macOS/Linux: Use the 'base64' command ($ base64 -i myfont.ttf -o fontbase64.txt).
   • Windows: Utilize a free/open-source Base64 encoder.

4. CSS Implementation: Use the encoded Base64 string in your CSS:

   @font-face {
       font-family: 'myfont';
       src: url(data:font/truetype;charset=utf-8;base64,<<copied base64 string>>) format('truetype');
       font-weight: normal;
       font-style: normal;
   }

By adhering to these steps, you can convert web fonts to base64 while maintaining their original look and feel.
