Frequently Asked Questions
What does HTML Sanitizer do?
The HTML Sanitizer remove unsafe html tags and attributes while keeping safe markup. It automates repetitive HTML tasks to save developers time and reduce manual formatting errors.
How do I sanitize HTML code?
Paste your HTML into the input editor and click the action button. The tool processes your markup instantly and outputs the result in the adjacent panel, ready to copy back into your project.
Does HTML Sanitizer preserve my formatting?
Yes. The tool intelligently preserves meaningful whitespace inside elements like <pre> and <textarea> while normalising indentation consistently across the rest of the document.
Can I preview the output?
Yes. A live preview pane renders the processed HTML in a sandboxed iframe so you can verify the visual result before copying the code into your project.
Is HTML Sanitizer compatible with HTML5?
Yes. The tool fully supports the HTML5 specification including semantic elements, custom data attributes, and void elements. Legacy HTML4 attributes are also handled without errors.
