HTML Beautifier
HTML Beautifier
Paste HTML to format it with clean indentation. Inline elements stay on the same line where that reads better.
The HTML Beautifier turns compressed or carelessly pasted markup into clean, indented code you can read, review, and edit with confidence. View-source output, email templates, and copied snippets rarely arrive tidy. When every tag sits on one line, matching opening and closing tags becomes a guessing game and small edits risk breaking the page.
This formatter works through your markup tag by tag, tracking nesting depth and indenting each level consistently. Block-level elements get their own lines, while inline elements such as links, spans, and emphasis stay on the same line as their surrounding text, because splitting them would make sentences harder to read, not easier. Void elements like images and line breaks are handled correctly with no closing tag invented for them.
The result is the same document, only organised. Nothing is uploaded; the beautifier runs as plain JavaScript in your browser, so it is safe for unpublished pages and client work.
How to use
- Paste your HTML into the box.
- Click Beautify HTML.
- Review the indented result and its line count.

Frequently asked questions
Does beautifying change how the page renders?
Formatting whitespace in HTML does not change rendering in normal cases, because browsers collapse extra spaces. One honest exception is preformatted text and a few whitespace-sensitive spots; check those areas if your page uses them.
Why do some tags stay on one line?
Inline elements like links and bold text are part of a sentence. Keeping them on the sentence's line mirrors how the content reads, which is how most style guides format HTML.
Can it fix broken HTML?
No. The beautifier organises markup; it does not repair mismatched or missing tags. Browsers and validators remain the right tools for finding structural errors.
Is my code uploaded?
No. Everything happens locally in your browser.
