How do I convert Google fonts .ttf file to other file to types to support all the browsers

I am going to use 'Open Sans' font. I downloaded the pack from google fonts directory. It has only ttf format files. I want all the file formats(EOT, SVG, WOFF) to support all browser. How to do this.

Solution

Google does not provide the other formats but neither you need to convert them yourself. You can download all font formats including X-Browser-CSS at http://localfont.com/

@font-face {
  font-family: 'Open Sans';
  font-weight: 400;
  font-style: normal;
  src: url('http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3fY6323mHUZFJMgTvxaG2iE.eot');
  src: url('http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3fY6323mHUZFJMgTvxaG2iE.eot?#iefix') format('embedded-opentype'),
       local('Open Sans'),
       local('Open-Sans-regular'),
       url('http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3ZBw1xU1rKptJj_0jans920.woff2') format('woff2'),
       url('http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3bO3LdcAZYWl9Si6vvxL-qU.woff') format('woff'),
       url('http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3aCWcynf_cDxXwCLxiixG1c.ttf') format('truetype'),
       url('http://fonts.gstatic.com/l/font?kit=cJZKeOuBrn4kERxqtaUH3Zbd9NUM7myrQQz30yPaGQ4&skey=62c1cbfccc78b4b2&v=v13#OpenSans') format('svg');
}
