HTML Minifier
The HTML minifier shrinks your HTML code for faster load times. It removes comments and excess whitespace but leaves scripts, styles and preformatted blocks untouched. Functionality is preserved while the file gets smaller.
What the minifier removes
- HTML comments
- Unnecessary spaces, line breaks and indentation in text
- Whitespace right next to the tag brackets
Content inside script, style, pre and textarea elements is protected so JavaScript and CSS stay intact. The tool shows the size saving in characters and percent.
Frequently asked questions
What exactly does the HTML minifier remove?
The minifier removes HTML comments, unnecessary spaces, line breaks and indentation, as well as whitespace right next to the tag brackets. The file gets smaller without its content changing.
Can the minifier damage JavaScript or CSS?
No. Content inside script, style, pre and textarea elements stays untouched. Your scripts and stylesheets are not changed and keep working after minification.
Why are certain elements protected?
Inside script and style blocks a space can be technically relevant. The minifier leaves these areas unchanged so the result works reliably.
How big is the saving?
The tool shows the size saving in characters and in percent. The actual saving depends on your source code and is especially high for heavily indented code.
Are my contents uploaded anywhere?
No. Minification runs entirely in your browser. Your HTML code is not transmitted to our server or stored.
Does the tool also work for large files?
Yes. Because processing happens locally in your browser, you can paste and minify larger files too. For very large files the processing time in the browser can increase.
