Minify HTML code instantly with our free online HTML minifier. This tool helps web developers reduce HTML file size by removing whitespace, comments, and unnecessary formatting for faster page loads. Simply paste your HTML and get minified output in real-time.
HTML Minifier reduces file size by removing unnecessary whitespace, line breaks, and optionally comments. This improves page load times and reduces bandwidth usage in production environments.
HTML minifier reduces file size by removing unnecessary whitespace, comments, and optional syntax. Smaller HTML means faster page loads and reduced bandwidth. Essential for production deployment optimization alongside CSS and JavaScript minification.
The minifier parses HTML and removes: extra whitespace between tags, HTML comments (except conditionals), optional closing tags, redundant attribute quotes, default attribute values. Output is semantically identical but smaller. Aggressive options can break some layouts.
Safe removals: comments, inter-tag whitespace, redundant quotes. Risky removals: whitespace in inline elements (affects text spacing), optional tags (affects CSS selectors), default attributes (may affect JavaScript). Use conservative settings initially, test thoroughly.

Use HTML minifier for production builds to reduce page size. Keep beautified source for development. Test thoroughly after enabling minification.
Typically 10-30% depending on original formatting. Well-commented, nicely indented code saves more. Already sparse code saves less. Combine with gzip compression for best results (gzip handles remaining redundancy).
