Frequently Asked Questions
What is an HTML beautifier?+
An HTML beautifier formats messy or minified markup with line breaks and indentation so the code becomes easier to read, edit, and debug.
How do I format HTML code online?+
Paste your HTML into the input box, choose an indent size, click Format HTML, then copy or download the formatted output.
Can I prettify minified HTML online?+
Yes. Paste one-line or compressed HTML into the tool and it will add readable line breaks and indentation around tags.
Is HTML beautifying the same as minifying?+
No. Beautifying makes HTML easier to read, while minifying makes HTML smaller for production use.
Does it change script or style content?+
The formatter preserves script, style, pre, and textarea blocks so their inner content is not aggressively reformatted.
Is my HTML uploaded to WebToolsEdge?+
No. Formatting, copying, and downloading all happen locally in your browser.
About this tool
Free HTML Beautifier
Use this free HTML Beautifier Online to format messy, minified, or hard-to-read HTML code directly in your browser. Paste markup from a webpage, CMS editor, email template, landing page, static file, or copied page source and turn it into readable HTML with clean indentation. An HTML formatter is useful when markup has been compressed into one line, copied from a page builder, generated by another tool, or mixed with nested tags that are difficult to review. Instead of manually adding line breaks and spaces, this tool separates tags, indents nested elements, and creates a cleaner structure that is easier to edit, debug, document, and share with another developer. You can use this tool to format HTML code online before reviewing a template, prettify HTML online after receiving minified markup, clean up snippets for documentation, or inspect page structure before converting content into another format. The formatter preserves script, style, pre, and textarea blocks so their inner content is not unexpectedly changed while the surrounding markup becomes easier to scan. Beautifying HTML is different from minifying HTML. A minifier makes code smaller for production, while a beautifier makes code readable for editing and troubleshooting. For a complete front-end workflow, you can format messy HTML first, make edits, and then compress the final version with an HTML minifier before publishing. All formatting happens locally in your browser. Your HTML is not uploaded to WebToolsEdge. Copy the formatted output or download it as a clean .html file when you are ready.
After formatting messy markup, compress the final version with the HTML Minifier, clean matching stylesheets with the CSS Minifier, or minify small scripts with the JS Minifier. For more front-end helpers, browse Developer Tools.
