HTML Formatter Online
Loading tool...
If you scrape a competitor's website or use an automated website builder, the resulting HTML code is usually a massive, unreadable wall of text. Trying to find a specific <div> in that mess is impossible. This beautifier is built to instantly parse raw markup and restore clean, hierarchical indentation.
Abstract Syntax Tree (AST) Parsing
This formatter doesn't just blindly insert line breaks after every > symbol. It parses the code into a structural tree, matching opening tags with their corresponding closing tags. It then applies strict indentation rules (which you can toggle between Tabs or Spaces) to visually nest child elements inside their parents.
Handling Self-Closing Tags
A common bug in cheap formatting tools is treating a self-closing tag like <img /> or <br> as an opening tag, which ruins the indentation for the rest of the document. This parser is pre-programmed with HTML5 specifications, so it correctly skips indentation on void elements.
The Inline Whitespace Trap
HTML is sensitive to whitespace between 'inline' elements. If a formatter forces a line break between a word and a <span> tag, it can accidentally inject a visible space into the rendered sentence on your live website. This algorithm safely keeps inline text blocks on the same line to preserve your exact visual layout.
