How to Use

1. Paste your raw HTML into the input field and configure which minification options to enable (comments, whitespace, attributes). 2. Adjust settings like collapsing boolean attributes, removing empty elements, and toggling quote normalization. 3. Preview the minified output instantly in the result panel — byte savings and compression ratio are displayed in real time. 4. Copy the minified HTML to clipboard or download it as an .html file for direct use in your project.

Why Use This Tool?

Manually minifying HTML is error-prone and interrupts your workflow — this tool handles whitespace collapsing, comment stripping, and attribute cleanup in one click with zero dependencies. It runs entirely in your browser, so no code leaves your machine and no npm install is required. Developers using it in staging pipelines or CMS workflows save 10–30% on HTML payload size without touching a build config.

Frequently Asked Questions

What is the HTML Minifier?
The HTML Minifier is a browser-based tool that removes unnecessary whitespace, HTML comments, redundant attributes, and optional tags from your markup to produce a compact, production-ready HTML string.
Does minifying HTML break inline scripts or styles?
Collapsing whitespace between tags is safe for almost all HTML, but aggressive minification of inline <script> or <style> blocks can occasionally alter behavior if those blocks contain whitespace-sensitive content. This tool targets HTML-level whitespace only and does not minify embedded JS or CSS content, keeping those blocks intact.
Is it free?
Yes — the HTML Minifier is completely free with no signup required. Built by the CanvasBuilder.co team.
