What beautification does
HTML beautification takes compressed or messy markup and adds consistent indentation, line breaks between elements, and proper nesting depth. One-line HTML becomes a readable document you can scan and edit.
This is useful when working with minified production code, CMS output that strips formatting, or email templates where everything ends up on a single line. Paste the markup, hit Beautify, and get something you can actually read.
The formatter uses js-beautify under the hood, with 2-space indentation and an 80-character wrap target. All processing runs locally in your browser. Nothing is uploaded.
HTML Beautifier FAQ
What does HTML beautification do?
It adds indentation, line breaks, and consistent formatting to make HTML readable. Tags are nested at the correct depth, attributes are spaced consistently, and the overall structure becomes easy to scan.
Will beautifying HTML change how my page works?
No. Beautification only affects whitespace and formatting. The structure, attributes, and behavior of your HTML remain identical. The page renders the same way before and after.
Can I beautify minified HTML?
Yes, that's the primary use case. Paste minified or single-line HTML and get readable, indented output. It also works on CMS-generated markup, email templates, or any HTML that's hard to read.
What's the difference between beautify and format?
They're the same thing. Both add indentation and line breaks to make code readable. You may also see it called "prettify" — same operation, different name.
