Google announced yesterday on the Google Code Blog the introduction of its new Font Previewer as part of the Google Font Directory, which was introduced back in May. Just as the name suggests, Font Previewer makes it easier for developers and designers to decide which web font in the Google Font Directory to use by testing and previewing each font.
The new Google Font Previewer allows users to preview and customize different font families. Users can change the size, spacing, variant, and even add shadows. The Font Previewer automatically generates the corresponding code to apply to a site. Additionally, the Font Previewer allows users to see the final result in an example window, without any distractions.
