TTF - Raw TrueType file, designed to look good on-screen.
EOT Lite - EOTs are only supported by Internet Explorer. This EOT type is uncompressed and is the same filesize as a TTF.
EOT Compressed - EOT compressed with LZ compression. File sizes are often smaller than WOFF. Special thanks to Richard Fink and Philip Taylor for creating the excellent EOTFast app.
WOFF - Cross-browser, web-only font format that uses gzip compression. IE9+, FF3.6+, Chrome 5+
SVG - This is an XML format required by iOS devices before version 4.2.
