Run the conversion and copy the inert text result.

Examples

Safe text conversion

Encode reserved markup characters or decode entities to plain, inert text.

Frequently asked questions

Can decoded output execute as HTML?

No. The result is inserted only as text inside a preformatted output panel. Scripts, SVG handlers, and tags never become DOM elements.

What happens to unknown entities?

Unknown, incomplete, out-of-range, and malformed entities remain unchanged so the tool never guesses silently.
