Manage font files

Learn how to manage your font files to sync them up along your font and text styles.


Sources like Figma and Tokens Studio manages TextStyle and Font design tokens as parameters applied to the fonts available on the host machine.

For both technical and legal reasons, Specify cannot extract font files from those sources, even though the SDTF is able to manage font files natively.

To bridge that gap, we'll share with you some techniques you can leverage to keep your font files in sync with your font and text styles tokens.


Before we start you need:

  • A Specify account with a repository

  • One or more font files in the following formats: 'ttf', 'woff', 'woff2', 'otf', 'eot'.

1. Host your font files

You are free to host your font files anywhere you can grab a public link to give Specify the ability to fetch the binaries.

We recommend using a company cloud storage like Amazon S3.

2. Create a SDTF tokens file

To register your font files to Specify, you need to create a SDTF JSON file containing your font tokens with the URLs from your cloud provider.

Note that you want to make the family property to match the font family used by your TextStyle or Font tokens.

3. Host your SDTF tokens file

To let Specify synchronize the font tokens into your repository, the SDTF JSON file must be hosted either privately or publicly.

Hosting on GitHub

  1. Create a new public or private repository on

  2. Add your SDTF JSON file containing the font tokens

  1. Grab the raw file URL by accessing the raw file over your browser

Hosting on JSONBin

  1. Create a new private or public bin on

  2. Place the content of your SDTF JSON file within it

  1. Grab the URL

4. Synchronize your tokens with Specify

You can now navigate to your Specify repository and head to "Sources" -> "Create source"

  1. Select the "Remote URL - Tokens Studio"

  1. Provide the URL to the font tokens file you created at step 3.

  1. (Optional) Provide authentication credentials for your provider. Read more about managing URL providers authentication.

  2. Select the "Specify Design Tokens Format" option

  1. Create the source. The sync is executed on the source creation and should take few seconds.

5. Sync the font files in your codebase

Once your new font tokens are synced into your Specify repository, you can start pulling the font-files to your codebase.

Let's have a look to one of the parser rule that can be used into any configuration file:

Once executed, the font files are available within the ./public/fonts directory.
