How to Use Our HTML Minifier
Our free online HTML minifier removes unnecessary characters from your HTML code without affecting functionality. Simply paste your HTML code, and the tool will automatically remove whitespace, comments, and optimize embedded CSS and JavaScript.
Best Practices for HTML Optimization
When minifying HTML for production websites, consider running the minified version through validation tools to ensure structural integrity. For complex JavaScript applications, test thoroughly after minification as some edge cases may require configuration adjustments.
Technical Details
The minification process works by parsing the HTML document structure and applying optimizations such as collapsing multiple whitespace characters into single spaces, removing HTML comments that don’t contain conditional comments, and minifying inline CSS and JavaScript blocks. The tool uses html-minifier, a widely-used library that handles complex HTML documents correctly.
Browser-Based Processing
All minification happens directly in your browser using JavaScript. No data is sent to our servers, making this tool suitable for processing confidential or proprietary HTML code. The entire operation completes in milliseconds for typical HTML files.
