What HTML Encoder Does

Encode special HTML characters to entity equivalents (&, <, >) to prevent XSS.

1.Paste HTML markup, text, or source code.
2.Special characters (&, <, >, ", ', /) are converted to HTML entity references.
3.Copy or download the safe encoded HTML string.

•Escaping user input before inserting into web pages to prevent XSS vulnerability.
•Displaying raw HTML code snippets inside code tags on websites.

Encoding prevents browsers from interpreting input as live HTML or JavaScript markup.

Decode HTML entities back into plain text safely.

Encode URLs or query string parameters to percent-encoded format.
