Bloated HTML snippets riddled with inline styles and proprietary tags often break modern CSS layouts when pasted into a CMS or static site builder.
Example Broken Input: A snippet from Microsoft Word contains tags like `
` which override your site's global styles.
Why it happens: Visual page builders and word processors prioritize layout over semantics, injecting 'poisoned' code that creates inconsistency and makes maintenance impossible.
Solution (Use Tool): Our HTML Cleaner strips away the noise - classes, inline styles, and proprietary attributes - leaving you with clean, semantic markup. The tool leverages your browser's native DOM parser to safely reflow code locally.
Advanced Notes: Use 'Strip All Tags' for high-speed text extraction if you only need the content without any markup for database storage or further analysis.
How to clean HTML
- Paste your dirty HTML code.
- Select your cleaning mode (Remove formatting vs Strip all tags).
- Copy the clean output.

DOM-Based Sanitization vs Regex Stripping
When cleaning HTML, two main approaches exist: regular expression matching and DOM-based parsing. Regex approaches use pattern matching to find and remove tags, but they are fundamentally unsafe for this task. HTML is not a regular language, which means regex cannot reliably parse nested structures, handle malformed markup, or account for edge cases like attributes containing angle brackets.
DOM-based sanitization, which this tool uses, leverages your browser's built-in HTML parser. The browser first constructs a proper document tree from whatever input it receives, automatically correcting unclosed tags, fixing nesting errors, and normalizing the structure. Only then does the tool walk the tree and remove unwanted nodes. This approach is inherently safer because the parser handles the complexity of real-world HTML before any cleaning logic runs.
Regex stripping can also be tricked by malicious input. A pattern like `
