Beautify and indent HTML markup instantly. Free online HTML formatter with custom indentation, attribute wrapping, and one-click copy — browser-based.
The Tooloogle HTML Beautifier reformats messy, minified, or machine-generated HTML into structured, readable markup. Whether you're inspecting a server response, cleaning up a CMS export, or formatting templates before commit, the beautifier turns one-line markup into properly nested, indented HTML.
HTML5, XHTML, and fragments
Embedded <script> and <style> blocks (formatted with the JS / CSS beautifier rules)
Templating syntax fragments (Vue / Angular / Handlebars-friendly)
Self-closing tags and void elements
Indent size — 2, 4, or 8 spaces, or tabs.
Wrap attributes — auto, force, or never (one attribute per line for tags with many attributes).
Preserve newlines — keep blank lines between blocks or collapse them.
Inline tags — configure which tags should stay on a single line (span, strong, a, etc.).
End-with-newline — ensure the file ends with a trailing newline.
Paste your HTML (or drop a .html file).
Pick your indentation and attribute-wrap settings.
Click Beautify — the formatted HTML appears instantly.
Copy or download the result.
Readable HTML makes accessibility audits, SEO reviews, and template debugging much faster. Properly indented markup reveals nesting bugs, missing closing tags, and structural issues that would otherwise hide in a wall of one-line text. It also produces clean diffs for version control.
Beautification happens entirely in your browser — your markup is never uploaded or stored.
