About this tool
There is no server behind HTML Decoder. HTML Decoder works on HTML in your browser, transforming or previewing the markup you paste locally.
Generated previews are escaped or sandboxed so pasted markup cannot affect the tool. It behaves the same on desktop and mobile, with nothing stored remotely.
