.dfont Type Fonts

Are .dfont type fonts usable on the web? I’m guessing they’re not. Though if I convert it to a true type font will it be usable?

.dfonts are for Mac users. They are not usable on the web. If you are attempting to use @font-face you need to have your fonts converted to several different filetypes for different browsers. Font Squirrel will do the conversions for you and will output an import CSS stylesheet so you can use them on your site.
