HTML Formatter
Format and indent HTML code for readability.
About HTML Formatter
HTML Formatter parses your HTML and rewrites it with consistent indentation, so nested elements are visually clear and easy to navigate. This is helpful when debugging markup that was hand-written inconsistently, minified for production, or generated by a tool. The formatter preserves inline elements and attributes while making block structure legible.

Frequently Asked Questions
Is HTML Formatter free?
Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.
Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
Will formatting change how my HTML renders in a browser?
No. Browsers ignore extra whitespace between block elements, so formatted HTML renders identically to unformatted HTML in virtually all cases.
Does it reorder attributes or change their values?
No. Attribute order and values are preserved exactly as you entered them.
