Format and indent HTML code for better readability
An HTML beautifier takes minified or messy HTML and reformats it with proper indentation and line breaks, so a wall of run-together tags becomes a clean, nested structure you can actually read. Production HTML is often minified — all on one line with no spacing — to save bytes, and HTML pasted from a page source, an email or a generator can be just as tangled. Beautifying reverses that: each element is placed on its own line and indented to show how tags nest inside one another.
Readable HTML is what lets you understand and edit a document: when the structure is laid out, you can see which tags are open, where a section begins and ends, and quickly spot an unclosed element that would otherwise be invisible in a single line. It is the counterpart to minifying — you beautify to work on the markup and minify the version you ship. This tool formats the HTML in your browser, so even private templates or page code never leave your machine.
No. It only adds whitespace and line breaks between tags, which the browser ignores for layout in normal flow. The page renders the same; the markup just becomes readable. The exception is whitespace-sensitive content like <pre> tags, which good formatters leave untouched.
Yes. Minifying strips whitespace to shrink the file for production; beautifying adds it back to make the markup readable for editing. The two are complementary — keep a readable source and minify the version you deploy.
Beautifying reformats and indents the markup, which makes structural problems like an unclosed tag much easier to see, but it does not rewrite your HTML to be valid. Use the clean output to spot and fix issues yourself, or pair it with a validator.
No. Formatting runs entirely in your browser, so the markup — including any private template or page code — is never sent to a server. You can safely beautify unreleased or internal HTML.
