HTML Minifier
Minify HTML online with conservative whitespace and comment cleanup while preserving scripts, styles, and whitespace-sensitive content.

What this HTML Minifier changes
The tool compresses repeated whitespace outside quotes in tags and attributes, removes obvious layout whitespace between tags, and drops ordinary HTML comments. It does not execute the page, load resources, upload source code, or render the HTML preview.
Why the minifying is conservative
HTML whitespace can affect visible copy, inline elements, template placeholders, email layouts, or signed snippets. To reduce risk, the tool preserves text nodes and keeps script, style, pre, and textarea content unchanged.
What to review after minifying
If your HTML includes template syntax, inline scripts, CSS, SVG, email-client compatibility code, conditional comments, or whitespace-dependent copy, test the output in the target environment. Minifying is not a build pipeline, XSS audit, or accessibility review.
FAQ
About this tool
Can HTML minifying change how a page looks?
Conservative minifying usually changes source layout only, but spaces between inline elements, pre or textarea content, scripts, and styles can affect output. This tool preserves those areas where practical, and important pages still need review.
Does this tool minify JavaScript or CSS?
No. script and style content is preserved so the tool does not corrupt code or styles. Use a language-specific tool when you need CSS or JavaScript minifying.
Are comments removed?
Ordinary HTML comments are removed. Conditional comments and bang-preserved comments are kept. Do not place licenses, compliance notes, or required markers in ordinary comments.
Does this tool upload my HTML?
No. The minifying step runs in the browser. You should still avoid pasting production secrets, customer data, unpublished page source, or confidential templates into pages you do not trust.
