Converting and Rendering Web Fonts to Base64 While Preserving Appearance

When implementing deferred font loading, it's crucial to encode fonts to base64 without compromising their original look. Here's a step-by-step guide to achieve identical rendering:

1. Configure Font Squirrel Webfont Generator: Ensure the "TrueType Hinting" option is set to "Keep Existing." This retains the original font hints, preserving its rendering.
2. Base64 Encoding from GWF File (Optional): Alternatively, you can use the font file directly from Google Web Fonts. Encode it to base64 using the command line (Mac/Linux):

$ base64 -i myfont.ttf -o fontbase64.txt

Or a base64 encoder tool (Windows).

3. CSS Implementation: Use the encoded font in your CSS with the following template:

@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 following these steps, you can successfully defer font loading on your site while maintaining the original font appearance, ensuring an optimal user experience.
