HTML Minifier

This tool removes conservative amounts of formatting whitespace from small HTML snippets so you can inspect a compact representation without sending the markup to a server.

Designed for: Frontend developers, technical writers, and site owners inspecting small HTML snippets.

How to use this tool

Paste a fragment or document. Conservative minify removes comments and whitespace between tags while keeping text content between tags. Readable format adds line breaks between tags for inspection.

How the result is produced

The browser applies regular-expression transformations intended for simple markup. It does not parse the input into a complete HTML document tree, which is why the page labels the output conservative.

Test examples

<div>\n <p>Hello</p>\n</div> becomes <div><p>Hello</p></div> under the conservative rule. Whitespace inside a text node is not treated as disposable.

Limitations

Do not use this as a production build pipeline. It may be unsuitable for preformatted text, inline scripts, inline styles, conditional comments, or markup where whitespace is meaningful. Always validate the result in the target browser.

Privacy and processing

The HTML is transformed locally in the browser and is not sent to the Nofyi server.
