Urban Fonts has an amazing collection of over 8,000 free fonts for you to download fonts. You can customize the look of the font previews by typing your own text in the input text field provided in all the font pages, or switch to an alphabetical view. The Names button switches your preview back to the name of the font. The colors of the text and background can be easily changed using the built in color picker. Urban Fonts also lets you choose how many fonts you’d like to have displayed in your page.
