What does Clean HTML do?

DOMPurify removes dangerous tags (script, style, iframe, etc.) and event-handler attributes while keeping safe structure.

What does Strip attributes do?

After sanitizing, tags remain but attributes are removed. Keep href/src/alt/title to preserve links and images, or strip all attributes for structure-only markup.

What do Text only and Markdown do?

Text only extracts visible text. Markdown converts common blocks (headings, lists, links, code) into a lightweight Markdown approximation.

No. Sanitization runs with DOMPurify in your browser.
