HTML Cleaner
Clean unnecessary styles, empty tags, inline attributes, and editor-generated HTML code.
What is an HTML cleaner?
An HTML cleaner helps prepare copied web markup, email templates, editor snippets, and test pages. You can separately remove ordinary comments, risky embeds such as script and iframe, event attributes such as onclick, inline styles, empty class or id attributes, and extra whitespace. The tool keeps destructive actions optional so you can choose an appropriate cleaning level before publishing or handing over markup.
How to use the HTML cleaner
- Paste HTML into the source area or load the example. The markup is processed in the current browser.
- Choose options for the use case. Keep inline styles disabled when styles are needed, and turn off empty-attribute or whitespace cleanup when you only want to remove scripts and events.
- Click Clean HTML, review the output against your page requirements, then copy it or download cleaned.html.
Key benefits of the HTML cleaner
Configurable cleaning
Options are independent: remove only event attributes or also remove risky embeds, styles, and whitespace to reduce accidental deletion.
Conditional comment support
Ordinary comments can be removed while conditional comments can be kept for templates that need legacy-environment compatibility.
Measurable output
The result shows output length and reduction percentage, making it easier to compare size and notice over-cleaning before download.
Browser-side processing
Source is processed in the current browser and does not need to be uploaded to a cleaning server. Follow your organization’s security policy for confidential content.
HTML cleaner frequently asked questions
What does Remove risky embeds delete?
It removes script, iframe, object, embed, applet, and form elements with their contents, which is useful for preparing safer static snippets. This can change page behavior, so confirm the purpose before cleaning forms or embeds.
Does the cleaner repair HTML structure?
No. It applies removal and whitespace rules; it does not add missing closing tags, reorder nesting, or repair invalid attributes. Use the HTML formatter and validator when structural repair is needed.
Is cleaned source uploaded?
Cleaning runs in the browser, and the tool does not actively upload source to generate the result. Downloads are saved locally; resources referenced by the source can still make their own requests.
