HTML Minifier & Beautifier — Free Online (No Uploads)

About this tool

This HTML Minifier & Beautifier is a quick way to make markup smaller or easier to read, without sending your code to a server. It runs entirely in your browser, so it is safe for private projects, drafts, or client work. Use it when you want a lighter HTML file for faster page loads, or when you need to clean up messy markup before editing.

Minifying HTML removes extra spaces, line breaks, and comments that browsers do not need to render a page. The file becomes smaller, which can improve load times and reduce bandwidth. Beautifying does the opposite: it adds clean indentation and consistent spacing so the structure is easier to scan and understand. This tool is conservative and avoids altering content inside <script>, <style>, <pre>, or <textarea> blocks to prevent breaking code or preformatted text.

To use it, paste your HTML into the input box, choose Minify or Beautify, and pick any options you need. Click the action button and the processed output appears instantly. You can then copy it into your editor, CMS, or build pipeline. For faster workflows, press Ctrl/Cmd + Enter to run Minify. Your last input is saved locally so you can return to it later.

The options let you control how aggressive the cleanup is. You can remove comments to reduce size, collapse whitespace between tags, trim extra spacing around attributes, or keep line breaks between block elements for a readable minified file. These switches are helpful when you need compact HTML but still want diff-friendly output.

Common use cases include optimizing landing pages, compressing HTML email templates, preparing files for static site generators, and prettifying HTML copied from a WYSIWYG editor. Whether you are working on a website, a web app, or a documentation page, this HTML formatter and minifier helps you go from messy markup to clean, lightweight code in seconds.
