The Problem with Unformatted HTML
Copy-pasted HTML from email templates, CMS outputs, or legacy codebases often arrives as a single wall of text. Nested divs collapse, attributes jumble, and indentation disappears entirely. The result: hours wasted on manual reformatting.

An HTML beautifier (also called an HTML formatter or pretty-printer) automatically:
- **Adds consistent indentation** to nested elements
- **Breaks long attribute lists** onto separate lines
- **Normalises whitespace** between tags
- **Removes redundant blank lines**
