Make an HTML document readable

Developers use HTML Formatter before a code review, debugging session or handoff to another contributor.

Make an HTML document readable, so reviews, edits and debugging become easier. Use it for free in your browser, with no account required.

How to use

Paste or import the HTML document you want to make more readable into the input area.
Run the formatting action to get an indented version that separates blocks and nested elements more clearly.
Scan the result and look for places where the indentation reveals unexpected structure or a tag that seems incorrectly closed.
Copy the formatted code into your editor, then test the page before delivering it or comparing it with another version.

Example

A developer might paste a compact HTML file received from a colleague, format it, and then review sections and nesting more easily. The result becomes a starting point for a review or a targeted fix.

Limits and formats

The tool does not validate HTML compliance and will not repair unclosed tags or invalid attributes.
Formatting adds spaces and line breaks, so check areas where these changes might matter, such as preformatted blocks.
It does not replace a full editor with version control, test execution and advanced syntax analysis.

Where processing happens

Formatting runs locally in your browser. The document you import or paste stays on your device and is not sent to any outside service.

Frequently asked questions

What is an HTML formatter for?

It reorganizes indentation and line breaks to make a document easier to read. This helps during a review, a debugging session or when taking over code.

Can I format CSS or JavaScript?

The import area accepts several web-related formats, including HTML, CSS, JavaScript, JSON, SQL and other text files. The result depends on the content and on what you need to inspect.

Will the result match the page rendering?

Not necessarily. Formatting mainly changes the source presentation. The browser rendering can stay the same if the HTML structure and styles remain correct.
