About HTML Beautifier
Minified HTML — whether pulled from a production site's view-source, an API response, or a build tool's output — is nearly impossible to read as one dense line. This tool rebuilds proper indentation by tracking each tag's nesting depth, turning compressed markup back into a structure you can actually scan and understand.
It correctly recognizes standard HTML void elements (like `<img>`, `<br>`, `<input>`, `<hr>`) that never get a closing tag, so it doesn't incorrectly increase indentation depth for them the way it would for a normal nested element. Opening tags increase indent depth, closing tags decrease it, and everything else lines up accordingly.
This is a common step when reviewing someone else's minified markup, debugging a template's output structure, or just making a scraped or copied piece of HTML readable enough to actually work with in an editor.
How it works
- Paste minified or messy HTML. Any single-line or inconsistently formatted markup.
- Structure rebuilds automatically. Nesting depth is tracked tag by tag.
- Copy the beautified result. Properly indented, readable HTML.
