HTML Bloat Detector

Catch copy-paste leftovers from Word, Figma, Google Docs, and rich-text editors. See exactly what's making your HTML messy.

What this tool catches and why it matters

Microsoft Word leftovers

When you paste from Word into a CMS or rich-text editor, Word's classes (MsoNormal, MsoTitle) and Office namespaces (<o:p>, xmlns:o) come along for the ride. They do nothing in browsers — they're pure bloat. They confuse AI engines parsing your DOM and bloat your file size.

Figma / design-tool auto-class names

Class names like frame-1234, Group-7, Rectangle-12 come from exporting Figma designs to code. They're meaningless for SEO, hard to maintain, and signal that the HTML wasn't crafted intentionally. Replace with descriptive class names.

Excessive nesting

Chains of <div><div><div><div><div> 5+ levels deep with no semantic meaning slow the browser, confuse screen readers, and make the DOM harder for AI engines to parse. Flatten.

Empty elements & consecutive <br>

Empty <p>, <div>, <span> tags and stacks of <br> are classic Word/Docs paste artifacts. They should be removed (or replaced with proper CSS spacing).

Inline styles overuse

Dozens of elements with the same inline style="..." attribute is a strong signal of copy-pasted content. Move repeated styles to a stylesheet — caches better, smaller HTML, easier to maintain.

Deprecated tags

Tags like <font>, <center>, <marquee> were removed from HTML5. Modern browsers still render most of them but they signal old or auto-generated HTML. Replace with CSS.
