How It Works

Our HTML formatter processes your code with these steps:

Parse HTML

The formatter indents the markup you paste. It does not run it in a browser or repair every broken tag.

Apply Indentation

Each level of nesting is indented with the number of spaces you selected.

Output Readable Code

The result is a beautifully formatted HTML block, ready for review or editing.

Format before committing to version control
Keep your HTML files under version control in formatted state

Formatting Benefits

Makes an unclosed tag easier to see than in one compressed line
Makes code reviews faster and more effective
Helps new team members understand the codebase quickly

An HTML formatting example

Paste this compressed fragment and set the indent to 2:

<section><h2>Shipping</h2><p>Leaves on Tuesday.</p></section>

The formatter puts the heading and paragraph on their own indented lines. It is a readability pass, using the js-beautify HTML formatter. It does not open the page in a browser, fetch missing images, or prove that every tag is valid.

If a tag is already broken, indentation will not reliably repair it. Fix the markup, then format the corrected copy.
