What is an HTML Beautifier?
An HTML beautifier takes minified or inconsistently formatted HTML and rewrites it with consistent indentation, making the nesting of elements clear and easy to follow. It's the opposite of minification — readability over file size.
How to Use This HTML Beautifier
- Paste your HTML into the input box.
- Choose 2-space or 4-space indentation.
- Click Beautify HTML to format it.
- Copy the result with Copy Output.
When Do You Need an HTML Beautifier?
Use an HTML beautifier when reviewing minified production output, cleaning up HTML pasted from a CMS or email export, or formatting templates that have lost consistent indentation after years of manual edits. Properly formatted markup makes it much faster to spot missing or mismatched tags.
Frequently Asked Questions
Why format HTML?
Formatted HTML with consistent indentation is far easier to read, debug, and maintain. It makes the nesting structure of elements visually obvious, which speeds up spotting unclosed tags or misplaced elements.
HTML minify vs beautify?
Beautifying adds whitespace and indentation for readability during development. Minifying removes whitespace to reduce file size for production. They serve opposite purposes at different stages of a project.
Does beautifying affect performance?
Beautified HTML is slightly larger due to added whitespace, but the difference is negligible for source files and has no effect on rendering — browsers ignore most whitespace between tags.
What are self-closing tags?
Self-closing tags like <br>, <hr>, <img>, <input>, <meta>, and <link> have no content and don't require a closing tag. This formatter recognizes them and skips increasing the indentation level after them.
