HTML Minifier
Minify HTML by removing whitespace and comments.
About HTML Minifier
HTML Minifier reduces the size of your HTML by stripping whitespace between tags, removing HTML comments, and optionally collapsing boolean attributes. Smaller HTML means faster page loads and lower bandwidth costs, which matters especially for high-traffic pages. The output renders identically in all modern browsers.

Frequently Asked Questions
Is HTML Minifier free?
Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.
Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
Does minification remove inline CSS and JavaScript?
The HTML Minifier focuses on HTML whitespace and comments. Inline CSS and JavaScript are preserved but not themselves minified — use the Code Minifier for that.
Can whitespace inside <pre> or <textarea> tags be affected?
No. The minifier respects whitespace-sensitive elements like <pre>, <textarea>, and <script>, leaving their contents untouched.
