COMMON QUESTIONS
HTML Cleaner FAQ
What does the online HTML cleaner remove?
It removes HTML comments, contenteditable and spellcheck editing attributes, common grammar-editor data attributes, empty class and id attributes, trailing spaces and excessive blank lines.
Will the cleaner remove JavaScript, CSS or accessibility attributes?
No. This conservative cleaner keeps script, style, event, data and ARIA attributes so it does not silently discard application behavior or accessibility information.
