What Is HTML Minification?
HTML minification is the process of removing unnecessary characters such as whitespace, comments and line breaks from HTML files without affecting functionality. This results in smaller file sizes and faster page loading times.
Why Minify HTML?
- Reduces page size
- Improves website loading speed
- Boosts Core Web Vitals
- Improves SEO performance
- Reduces bandwidth usage
How HTML Compression Works
The minifier removes comments, collapses multiple spaces, trims unnecessary newlines and merges tags efficiently while keeping visible content unchanged.
Difference Between Minification and Gzip
Minification reduces code size permanently, while Gzip compression happens at server level during file transfer. Both should be used together for best performance.

Our algorithm preserves important spaces inside text nodes and attribute values, ensuring that layout and functionality remain unaffected.
