How to Install Fonts on Windows, macOS, and Linux

You downloaded a font. Now what? Installing it takes under a minute on any system. Here's how on each.

Windows

Unzip the download, right-click the .ttf or .otf file, and choose Install (or "Install for all users" if you want it system-wide). The font appears in apps immediately — you may need to restart an app that was already open.

macOS

Double-click the font file to open Font Book, then click Install Font. macOS validates the file and adds it. You can organize fonts into collections in Font Book later.

Linux

Copy the file into ~/.local/share/fonts/ (for your user) or /usr/share/fonts/ (system-wide), then run fc-cache -f to refresh the font cache. The font is then available to GTK and Qt apps alike.

Tips that save headaches

• Install the whole family, not just one weight, if you want bold/italic.
• If a font doesn't show up, fully restart the application.
• Variable fonts install the same way and expose their weights in modern apps automatically.

That's it — the same downloaded file works across all three systems.
