It’s pretty easy. After purchasing a webfont license available exclusively on our site, you’ll receive WOFFs, WOFF2s and EOTs you can host yourself along with a link to send your fonts to Typekit. If you already have a Typekit account, the fonts can be added to your existing plan at no additional charge. If you’re a new Typekit user, you can host the fonts with any of their plans, including their free Trial plan.
To send the fonts in your order to Typekit, log in to your Process account, find your order and click ‘Use Typekit’. You’ll be sent to Typekit’s website where you can log in to an existing account or start a new one. Once you’ve logged in, the fonts will be available in your Typekit account. Keep in mind the link to activate the fonts can only be used once.
You also have the option of purchasing the fonts through Typekit Marketplace. While you’ll get the benefit of their webfont hosting and desktop sync services, you won’t get any font files.
