HTML Minifier / Beautifier

What does the HTML minifier and beautifier do?

This tool processes your HTML code in two ways: minification removes comments, whitespace and empty elements to reduce file size and speed up page loading; beautification formats the code with indentation and line breaks so it is easier to read, debug and maintain. Everything runs in your browser, without sending your code to any server.

How to use this tool

1. Paste your HTML code into the input panel or load the sample with the "Sample" button.
2. Tick the minification options (comments, whitespace, empty elements) or choose the beautify indentation.
3. Press "Minify" or "Beautify" and the result appears instantly in the right panel.
4. Check the size reduction in the statistics, copy the result or download it as an .html file.

Typical use cases

• Minify HTML templates before deploying to production to improve web performance.
• Beautify auto-generated code to review it or document it.
• Compare a file weight before and after optimization to measure the real improvement.

Frequently asked questions

Does minification break HTML code?

No. Only comments and whitespace between tags are removed, which browsers ignore. Content inside tags such as pre, script or textarea is kept intact.

Is my code sent to any server?

No. Processing is 100% local in your browser via JavaScript. Your code never leaves your device.
