Font Awesome Free
Icon Validator

The Font Awesome Free Icon Validator is an advanced validation tool with AI-powered migration guides. It validates icons from code OR public URLs, auto-detects icons from live websites, and exports AI-ready fix guides in Markdown, JSON, or CSV format. Perfect for migrating between Font Awesome 4, 5, 6, and 7 with 135+ verified migrations.

Paste your HTML, CSS, or code into the validator, or enter a public URL to scan a live website. Click 'Validate Icons' and the tool will instantly show which icons are available in Font Awesome Free and which require a Pro license. You can also export AI-ready migration guides to automatically fix issues.

Yes! You can enter any public URL and the validator will automatically fetch and scan the website's HTML and CSS to detect all Font Awesome icons in use. This is perfect for auditing live websites, reviewing third-party themes, or checking icon usage without downloading files.

The AI export feature generates ready-to-use migration guides in Markdown, JSON, or CSV format that you can directly provide to AI assistants like Claude, ChatGPT, or Gemini. The AI can then automatically fix your Font Awesome icons based on these comprehensive guides with 135+ verified cross-version migrations.

Yes! The validator supports Font Awesome 4.7.0 (730 icons), 5.15.4 (1,608 icons), 6.0.0 (1,895 icons), 6.7.1 (1,895 icons), and 7.1.0 (1,918 icons) with 135+ verified cross-version migrations. All migrations have been validated against actual icon data to ensure 100% accuracy.

The validator supports HTML, CSS, React (JSX), Vue, Angular, Svelte, and SolidJS. It can detect Font Awesome icons in any code format and even from live websites via public URLs. The parser intelligently handles class attributes, CSS selectors, and framework-specific syntax.

All 135+ FA5→FA6→FA7 migrations have been manually verified against actual Font Awesome icon data to ensure 100% accuracy. The validator cross-references icon names, styles (solid/regular/brands), and availability across all supported Font Awesome versions. When an icon doesn't exist in your target version, the validator provides smart suggestions for free alternatives.

Yes! When you upload local files, the validator tracks the exact file path, line number, and column position of every Font Awesome icon detected. Export these locations in your AI migration guide and your AI assistant can automatically fix every single instance across your entire project without manual searching.

No! All validation happens 100% client-side in your browser. Your code, uploaded files, and validation results never leave your device. The validator works completely offline as a Progressive Web App (PWA). The only exception is when you use the "Scan URL" feature, which fetches public websites from the internet.

The validator exports results in three formats: Markdown (.md) for documentation and AI context, JSON (.json) for programmatic processing, and CSV (.csv) for spreadsheet analysis. All exports include icon names, styles, Free/Pro status, file locations (when available), and suggested migrations. The "AI Fix Guide" export is specifically optimized for Claude, ChatGPT, Gemini, and other AI assistants.
