See Full FAQHTML minification is the process of removing unnecessary characters (whitespace, comments, etc.) from HTML files to reduce file size. It's important because: Reduces file size, leading to faster page load times Improves website performance and user experience Decreases bandwidth usage and server costs Enhances SEO rankings through better page speed metrics Can minify inline CSS and JavaScript for additional savings
No, our HTML minifier is designed to preserve all HTML functionality while removing only unnecessary characters. The minified HTML will behave exactly the same as your original HTML, just with a smaller file size. However, we recommend testing the minified HTML in your development environment before deploying to production.
Each level provides different compression: Light: Removes comments and basic whitespace while maintaining readability Medium: Standard minification with whitespace collapsing and attribute optimization Aggressive: Maximum compression with all optimizations enabled, including optional tag removal and inline code minification
Yes! The tool provides granular control over optimization features. You can toggle options like comment removal, whitespace collapsing, attribute quote removal, empty attribute removal, optional tag removal, inline CSS/JS minification, URL minification, and more. This allows you to customize the minification process based on your specific needs.
Yes! When enabled, the tool can automatically minify inline CSS within <style> tags and inline JavaScript within <script> tags. This provides additional file size reduction beyond just HTML minification.
Currently, the tool processes one HTML file at a time. For multiple files, you can upload and minify them individually, or combine them into a single file first. We recommend minifying each file separately to maintain better organization and easier debugging.
File size reduction varies depending on your HTML. Typically, you can expect 20-40% reduction with standard minification, and up to 50-70% with aggressive optimization settings. The actual reduction depends on factors like the amount of whitespace, comments, and redundancy in your original HTML.
Yes, the minified HTML is production-ready and can be used directly in your live website. However, we always recommend keeping a backup of your original HTML file and testing the minified version thoroughly before deploying to ensure everything works as expected.
