URL Encoder and Decoder — Encode a Query Value
Encode or decode one URL component with percent escapes, including spaces and Unicode text, in your browser.

How to use it
Paste a query parameter value and choose encode or decode.
Good to know
Encoding is for a component, not an entire navigable URL. Malformed percent sequences produce an error.
Encode the value, not the whole address
Use this tool when a piece of text needs to go inside a query parameter or path component. For example, encoding Paris & Ada/✓ produces Paris%20%26%20Ada%2F%E2%9C%93. The escaped %26 prevents the ampersand from being read as the start of another query parameter.
To build a URL manually, keep its structure separate: https://example.com/search?q= plus the encoded search value. If the value is red shoes & socks, append red%20shoes%20%26%20socks, not an encoded version of the entire URL.
Decode copied parameter values
Choose Decode to turn a component such as red%20shoes%20%26%20socks back into readable text. Malformed percent escapes, such as %ZZ, cause an error rather than a partial result. A plus sign is left as a plus sign because this tool uses URL-component encoding, not HTML form decoding where + can mean a space.
Encoding makes reserved characters safe to transport; it does not make a link private or safe. Do not put passwords, access tokens, or sensitive personal data in URLs. Review the destination system’s requirements for a full URL, path segment, or form body. Text up to 100,000 characters stays in your browser.
