Fontsource for Obsidian

Fontsource imports fonts from the Fontsource directory and makes them available throughout Obsidian, including popout windows.

This version requires Obsidian 1.12 or newer.

Usage

1. Open Settings → Fontsource.
2. Import a font from the Fontsource directory.
3. Enable the imported font.
4. Choose where to use it: interface, text, or monospace.

Multiple fonts can be selected for each role and ordered by precedence to cover additional languages.

Network and storage

The plugin connects only while listing or importing fonts:

• api.fontsource.org provides the font directory and metadata.
• cdn.jsdelivr.net provides the selected WOFF2 font files.

Imported fonts are encoded into CSS files under your vault's configured Obsidian folder at fonts/<font-id>.css. The plugin reads and writes only those cache files through Obsidian's vault adapter and stores your selections in its normal plugin settings. Once imported, fonts load from the local cache.

Development

This project requires Node.js 22.13 or newer and pnpm 11. CI uses Node.js 24.
