HTML Formatter

Paste your HTML below to format and beautify it instantly. Proper indentation makes HTML readable and easier to debug.

What is HTML Formatting?

HTML formatting is the process of adding proper indentation and line breaks to HTML code to make it readable. When HTML is minified or generated by a tool it often comes as one long line with no spacing. That is fine for browsers but makes it very hard for developers to read and debug.

A formatted HTML file shows the structure of the document clearly. You can see which elements are nested inside which, where tags open and close, and how the page is organised. This makes it much easier to find and fix bugs.

How to Use This Tool

  1. Paste your HTML into the left input box.
  2. Choose your preferred indentation - 2 spaces, 4 spaces, or tabs.
  3. Click Format HTML to see the beautified output on the right.
  4. Click Copy Output to copy the formatted HTML to your clipboard.

Frequently Asked Questions

Will formatting change how my page looks?

No. HTML formatting only adds whitespace which browsers ignore when rendering pages. Your page will look and behave exactly the same after formatting.

Is my HTML sent to a server?

No. Everything runs entirely in your browser. Your code never leaves your machine.

Can I format HTML with inline CSS and JavaScript?

Yes. This tool formats the HTML structure. Inline styles and script content are preserved as-is.
