Local Font Access API browser support

window.queryLocalFonts() returns a promise for an array of FontData objects describing the fonts installed on the user’s device, behind a local-fonts permission prompt.

The table covers the method as recorded in MDN browser-compat-data (api.Window.queryLocalFonts). The open Chromium bug for Android support is linked from the Android rows.

Call requirements

The method is available only in secure contexts. It throws a SecurityError when called without prior user interaction or when a Permissions Policy blocks the feature, and a user-denied prompt rejects with NotAllowedError (MDN). The returned list is not guaranteed to be complete or to follow the filesystem order.
