Why Messy HTML Can Break Your Website
When you copy and paste from Microsoft Word, Google Docs, or other web pages, text that looks neat actually carries a lot of hidden <span> tags, class attributes, and inline style properties. When pasted into a CMS editor, these attributes often override your site's own CSS — resulting in random font changes, inconsistent text sizes, or colors that don't match your theme.
What This Tool Cleans
This tool works using a tag whitelist approach — only basic semantic tags are kept, while the rest are unwrapped (the content stays, only the wrapper tags are removed):
- Retained tags:
b, i, u, strong, em, p, br, ul, ol, li, img, h1-h6, table, thead, tbody, tr, td, th, caption, a - Retained attributes: only
src, alt, title, loading, width, height, srcseton images, andhrefon links — allclass,id,style, and other attributes are automatically removed - Additional cleanup:
<div>tags are unwrapped (content is preserved), and citation marks such as[1]or[1, 2]are automatically removed — useful for content pasted from AI research results
The Difference Between an HTML Cleaner and an HTML Formatter/Beautifier
These two terms are often confused. An HTML formatter only tidies up code indentation and spacing to make it readable, without deleting any content. An HTML cleaner — like this tool — actively removes unwanted tags and attributes. If your goal is visually neat code, use a formatter; if your goal is code free of clutter before publishing, use a cleaner.
How to Use the Clean Output in Blogger and Other CMS Platforms
The result from this tool is plain HTML, so it can be pasted directly into any CMS without extra plugins:
- Open your post in Blogger, and click the HTML view tab in the editor.
- Paste the cleaned result copied from the tool above.
- Switch back to the Compose tab to make sure the formatting matches your site's theme rather than the content's original theme.
