Free Code Minifier Guide — HTML, CSS, JavaScript

Minifying code removes unnecessary characters (whitespace, comments) to reduce file size and improve page load speed. This guide covers how to minify HTML, CSS, and JavaScript.

What gets removed?

• HTML: Comments, extra whitespace between tags
• CSS: Comments, whitespace around punctuation
• JavaScript: Comments, whitespace (safely — preserves regex and division)

The AHX Code Minifier uses a safe JS minification approach that avoids breaking regex literals and division operators. It shows the size savings percentage and lets you download the minified file.
