Free online HTML formatter, pretty printer, and minifier
This free HTML beautifier pretty-prints messy markup in your browser. Use it as an HTML formatter to indent tags, or minify HTML for a smaller payload. Beautify HTML with 2 or 4 spaces, keep inline text readable, and copy the result. Nothing is uploaded.

Paste HTML, then Beautify. Ctrl or Cmd + Enter.
Drop a file anywhere on the editor. Formatting never leaves this tab.
Minified templates, scraped pages, and email HTML are painful to read. An HTML beautifier restores structure: each block tag on its own line, children indented, phrasing content such as <strong> and <a> kept with the surrounding text so you do not lose word spacing.
That is the same idea as an HTML pretty printer or tidy: the document should look the same in a browser, just easier for humans and diffs.
Block structure (html, body, div, ul, table, headings, and similar) is nested. Void tags such as img, br, and meta stay empty. Comments and doctype declarations keep their place at the top of the tree.
Inside <script>, <style>, <pre>, and <textarea> the original text is left alone. Beautifying CSS or JS in those bodies would risk breaking strings and already-minified bundles.
<p>Hello <strong>world</strong>.</p> <ul> <li>One</li> <li>Two</li> </ul>
Keyboard shortcut: Ctrl+Enter or Cmd+Enter runs Beautify. Tab inserts the current indent.
An HTML beautifier (also called an HTML formatter or HTML pretty printer) takes minified or messy markup and rewrites it with consistent indentation and line breaks so you can read, diff, and edit it.
Paste your HTML into the editor and click Beautify. The formatter indents block tags, keeps inline phrasing on one line, and preserves the contents of script, style, pre, and textarea.
Yes. HTML beautifier, HTML formatter, pretty print HTML, and tidy HTML all describe the same job: make markup readable without changing how the browser renders it.
Yes. Minify removes extra whitespace between tags while leaving script, style, pre, and textarea bodies intact so your page still works.
No. Formatting runs entirely in your browser. Markup never leaves your device, which makes it safe for unpublished pages and internal templates.
Whitespace in HTML is mostly insignificant outside pre, textarea, and CSS white-space. This beautifier keeps those elements intact. Inline text stays on one line so you do not drop spaces between words.
It pretty-prints the HTML around style and script tags. The CSS and JavaScript inside those tags is preserved as-is so you do not break strings or minified bundles.
Yes. Free, no signup, and no document-size limit beyond what your browser can hold.
