Webfont Checker

Overview

Webfont Checker is a powerful tool designed to analyze the fonts used on a WordPress website. It scans all internal pages, detects which fonts and font-weights are actively used, and identifies unnecessary fonts loaded via @font-face or preload links.

This tool is particularly useful for optimizing performance by removing unused webfonts, reducing page load times, and improving overall efficiency.

Features

• Automatic site crawling: Scans all internal pages to ensure complete font analysis.
• Font weight detection: Identifies all font-weights used across the website.
• Preload & @font-face analysis: Detects fonts loaded via @font-face rules and preload links.
• Identifies unused fonts: Helps optimize performance by suggesting font removals.
• Supports WordPress WP-CLI: Easily integrate with WordPress via WP-CLI commands.

Requirements

• Node.js (must be installed and available in the system path)
• Puppeteer (automatically installed if missing)
• WP-CLI (WordPress Command Line Interface)

Installation

1. Install via Composer

composer require mintis/webfont-checker --dev

2. Activate WP-CLI Command

After installation, WP-CLI should automatically register the webfont command. To verify installation, run: wp webfont scan

If the command is not found, ensure WP-CLI is properly installed and that the package is correctly registered.

Usage

Running a Font Scan

To perform a full scan of your website, use the following command: wp webfont scan
