Beautify and format HTML markup with indentation
About HTML Formatter
How HTML Formatter Works
Paste markup and it is indented and structured in your browser, respecting scripts and styles. The process is fully client-side, so your HTML is never uploaded or stored.
The HTML Formatter beautifies raw or minified markup by adding proper indentation and line breaks, turning unreadable blobs into structured documents. A typical use case is tidying up HTML scraped from a page or produced by a templating engine so you can actually read and edit it. The formatter handles inline styles, script tags, and nested elements, preserving the document's meaning while improving clarity. Everything runs in the browser, so the markup you paste is never transmitted. Clean HTML is easier to maintain, debug, and hand off to teammates, and it makes accidental nesting mistakes far more visible during review.
Frequently asked questions

Limitations
It improves readability, not validity. Malformed HTML may still need a validator to catch real errors.
