HTML Formatter (pretty-printer) takes messy, minified, or unindented HTML and outputs clean, consistently indented markup. Readable HTML is easier to debug, review in version control, and maintain. The formatter handles nested tags, inline vs. block elements, and self-closing void elements according to HTML5 conventions, all without modifying the actual content of your markup.
How it Works
1Paste your raw or minified HTML into the input panel.
2The formatter parses the markup and rebuilds it with proper nesting and indentation.
3Inline elements (span, a, strong, etc.) are kept on one line; block elements (div, p, section, etc.) each start on a new line.
4Copy the formatted output directly or download it as an .html file.
Frequently Asked Questions
Will formatting change how my HTML renders in a browser?
No. HTML parsers ignore extra whitespace between block-level elements. The formatted output renders identically to the original in every browser.
Can I format HTML that contains embedded CSS or JavaScript?
Yes. Inline <style> and <script> blocks are detected and their contents are left intact. The formatter focuses on the HTML structure and does not attempt to reformat embedded code.
What indentation style does the formatter use?
The default is 2-space indentation following common web development conventions. Nested elements are indented by one additional level per depth.
Can I format HTML email templates?
Yes. HTML email templates are standard HTML and the formatter handles them correctly. Just note that email clients are more sensitive to whitespace in certain inline contexts — review the output before sending.
