About this HTML Minifier
The HTML Minifier removes HTML comments and collapses unnecessary whitespace between tags to reduce file size. It is useful for preparing production markup without manually stripping formatting.
For related tasks, try Markdown to HTML Converter, HTML Entity Encoder / Decoder or JSON Formatter & Validator.
How the calculation works
The tool removes text matching HTML comment syntax, then collapses runs of whitespace between tags into a single space and trims the result.
How to use it
- Paste HTML markup into the box.
- Select Minify.
- Copy the compacted HTML.
Practical example
Multi-line, indented HTML with comments is reduced to a single compact block with comments removed and extra whitespace collapsed.
Frequently asked questions
Does it minify inline CSS or JavaScript inside the HTML?
No, only the HTML structure and whitespace are affected.
Could minifying change how the page displays?
Whitespace-sensitive elements such as <pre> can be affected by aggressive whitespace collapsing, so review the result for such content.
Is this reversible?
No, minifying removes formatting; keep your original formatted file separately.
