HTML Cleaner & HTML Stripper — Everything You Need to Know
Whether you're a developer cleaning up CMS output, a copywriter extracting text from a webpage, or a designer removing messy Word-pasted markup, an HTML code cleaner is one of the most useful tools in your workflow. Our free, in-browser HTML cleaner handles everything from removing comments and scripts to full HTML stripper mode for pure plain text.
What is an HTML code cleaner?
An HTML code cleaner is a tool that takes raw HTML input and removes or reformats unwanted elements. Common tasks include stripping HTML comments (<!-- ... -->), deleting embedded <script> and <style> blocks, removing inline style="" attributes left over from email clients or word processors, and prettifying the resulting markup with clean indentation.
HTML stripper mode — extract plain text instantly
The HTML stripper option removes every single HTML tag from the document, leaving only the text content that a user would see in a browser. This is invaluable for feeding content into AI tools, running word counts, importing into spreadsheets, or anywhere you need the text without the markup. Simply enable "Strip all tags (plain text only)" and click Clean HTML.
Cleaning HTML from Word, Google Docs, and email clients
Content copied from Microsoft Word or Google Docs into a CMS typically brings a storm of inline styles, class attributes, and span tags. Email templates from tools like Mailchimp or Constant Contact likewise embed heavy inline CSS. The HTML code cleaner's attribute-cleaning options let you strip all of that in one click, giving your team clean markup they can actually maintain.
When to use the prettify option
The prettify option re-indents your HTML with consistent 2-space indentation on block-level elements. This is ideal after minifying a file for production — if you need to read it again later — or after running through a templating engine that collapses all whitespace. Readable code is easier to debug and review.
HTML cleaner vs. HTML validator
A cleaner removes unwanted content; a validator checks whether your HTML is syntactically correct. Use the HTML code cleaner first to remove noise, then run the result through a validator (such as the W3C Markup Validation Service) to catch structural errors. The two serve different purposes but work well in sequence.
Removing inline event handlers and tracking scripts
HTML from landing page builders, marketing tools, or third-party widgets often contains inline event handlers — onclick="", onmouseover="", onload="" — alongside embedded tracking pixels. These are a maintenance problem and a potential security issue when importing content into a CMS that serves the markup to other users. The attribute-cleaning option strips these in one pass, leaving the structural markup intact.
Content syndicated from external sources may also arrive with embedded <script> tags, iframes, or surveillance pixels. Removing all of these when you enable the relevant options leaves you with just the content — headings, paragraphs, links, images — without the third-party javascript or tracking markup baked in.
Cleaning HTML for use in email templates
Email HTML is a specific kind of mess. Email clients like Outlook, Gmail, and Apple Mail all render HTML differently, and the resulting templates accumulate hacks over time — conditional comments for Outlook, inline styles overriding inline styles, table-based layouts nested six levels deep. When you need to audit or migrate an email template, cleaning it first makes the underlying structure readable.
The "remove inline styles" option is useful when you're moving a template from inline CSS to a stylesheet approach (which modern email clients increasingly support). For plain-text email fallbacks, the HTML stripper mode gives you the raw text in seconds — no need to manually paste and delete tags.
Security: what this tool is and isn't
This tool is for manual, one-off cleaning — not for sanitising untrusted HTML at runtime in a production system. If you're building a product that accepts HTML from users (a forum, a CMS, a comment field), you need a proper sanitisation library: DOMPurify for JavaScript environments, html-sanitizer for Python. Those are actively maintained security tools with documented threat models. This tool is useful for developers who need to manually clean HTML before pasting it into a database, writing it to a file, or sending it in an email.
What to do after cleaning
Once you've stripped the HTML, you might want to convert Markdown sections that arrived mixed in, format the remaining stylesheet content, or compress any extracted JavaScript. The Markdown to HTML converter handles Markdown blocks. The CSS minifier compresses any extracted style blocks before you re-embed them. And if you're building a broader developer workflow, the JS minifier processes extracted script content without touching your cleaned HTML.
