What is an HTML Minifier?
An HTML minifier is a tool that reduces the file size of HTML documents by removing unnecessary characters: whitespace, comments, optional end tags, and redundant attributes: without changing how the page renders in a browser. Smaller HTML files load faster, consume less bandwidth, and improve your website's Core Web Vitals scores.
CodeHelper's HTML Optimizer uses a professional parser engine and can reduce HTML size by up to 70%, while also offering a beautify mode to format messy HTML for readability.
Minify vs. Beautify HTML
- Minify: Remove all whitespace, comments, and optional tags to produce the smallest possible output for production deployment.
- Beautify: Add proper indentation and line breaks to unformatted or minified HTML for easier editing and code review.
- Advanced Options: Choose to preserve certain comments, keep
<pre>and<code>content intact, normalize boolean attributes, and remove default type attributes.
