Chances are that within your branding
Chances are that within your branding, you’re using at least one custom font to give your business a unique look through typography. To apply this custom font to your website, you will need a file containing it in various formats. If you’re working with a graphic designer, they’ll likely provide you with your font files, including the OTF and WOFF format. Without these files, your web designer cannot upload and use your customized typography onto your website.
