How to open by OS

  • Font Book to preview and install.

Linux

  • Drop into `~/.local/share/fonts` and run `fc-cache`.

Ios

  • Install via Configuration Profile or a font-management app.

Safety notes

  • Historical TrueType rendering RCEs (e.g. Windows Font driver CVEs) have granted OS-level code execution. Keep systems patched.

Common mistakes

  • Serving TTF directly on the web is inefficient. Convert to WOFF2 for ~3-4x smaller transfer.
  • Embedding commercial fonts without reading the license often violates the EULA.
