Encode URL values or full URLs, and decode percent-encoded text with input validation.
Use for a query parameter or another single URL value.
Enter text to see the result.
Percent encoding replaces characters that have a special meaning in a URL with a percent sign and a byte value.
Choose single-value mode for query values and full-URL mode when you want to preserve URL separators such as slashes and question marks. Decoding reports malformed percent sequences as an error.
Prepare user input for a query parameter, or inspect an encoded link while debugging a request.
