Does it minify inline CSS and JavaScript?

Yes. It can minify CSS inside tags and JavaScript inside tags when those options are enabled.

Will this change how my webpage works?

The tool uses safe minification, but you should always test important pages after minifying.

Is my code uploaded to a server?

No. The tool runs in your browser and does not upload your code.

Can I download the minified HTML file?

Yes. Use the Download .html button to save the minified output as an HTML file.

Should I use this before production?

For quick static pages, landing pages, and snippets, yes. For large apps, a build tool such as Vite, Webpack, or a production pipeline is still recommended.

Download minified .html

Save the minified output as a standalone HTML file for local testing or quick deployments.

Privacy note

The minifier runs locally in your browser without any backend API or upload.

Security note

Output is shown as text only. Pasted HTML, CSS, and JS are never executed by this tool.

Accuracy note

JavaScript is minified conservatively to avoid breaking code. Always test important pages after minifying.

Reset or try example

Load a realistic example page or clear the editor to start fresh.

Minification options

Pick the safe transformations you want applied to your webpage source.

Remove HTML commentsStrip standard HTML comments from markup.Minify inline CSSCompress styles inside <style> tags.Minify inline JavaScriptConservative cleanup for inline <script> tags.Collapse whitespaceReduce repeated spaces and line breaks between tags.Preserve conditional commentsKeep  blocks intact.Preserve pre / code / textareaKeep whitespace-sensitive content untouched.

Safe browser-side minification

This tool focuses on safe, conservative transformations. It does not rewrite selectors, mangle JavaScript identifiers, or remove unused HTML/CSS/JS. Use a production build pipeline for advanced optimisation.

Developer guide

Minify a complete webpage in one step

Compress HTML markup, inline CSS, and inline JavaScript from a single source to reduce page weight before deployment.

What is an HTML/CSS/JS Minifier?

It compresses a full webpage source by removing unnecessary comments, whitespace, and formatting from HTML, inline CSS, and inline JavaScript while preserving page behaviour where possible.

What does this tool minify?

HTML structure, inline CSS inside <style> tags, inline JavaScript inside <script> tags, HTML/CSS/JS comments where safe, and repeated spaces and line breaks between tags.

When should you use it?

For static HTML pages, landing pages, email templates, embedded widgets, small frontend snippets, testing size reduction before deployment, and cleaning generated HTML.

Is browser-side minification safe?

The tool runs in your browser, code is not uploaded, and it uses conservative minification. Always test important pages after minifying.

HTML/CSS/JS Minifier vs separate minifiers

Separate CSS and JS minifiers are useful for standalone files. This tool is better when your source already has inline CSS and JavaScript in a complete HTML page.

How is JavaScript handled?

JavaScript is minified conservatively: comments are removed outside strings, whitespace is collapsed safely, and newlines around statements are preserved so automatic semicolon insertion is not affected.
