Frequently Asked Questions

How are fonts detected?

Font detection uses the browser's <code>document.fonts</code> API and a curated list of common system fonts. Only fonts installed on your local system that are accessible to the browser are shown.

Why are some system fonts not showing?

Browser security restrictions limit access to locally installed fonts. Some fonts may not be accessible to web pages. The common system fonts list provides fallback references for standard OS typefaces.

Is this tool free?

Yes, PivaBox Font Preview is completely free to use. All font detection and rendering happens locally in your browser.
