What is URL encoding?

URL encoding (percent-encoding) replaces unsafe or reserved characters with a % followed by two hex digits so URLs remain valid.

How do I encode a URL?

Paste the text or query value into the Encode tab. This tool applies encodeURIComponent-style encoding in your browser.

Open Decode, paste the encoded string, and read the restored text. Incomplete % sequences produce an error.

%20 is the encoded form of a space. Many systems also accept + for spaces in query strings; this decoder treats + as a space when decoding.

Encode user input that becomes part of a path or query string, especially for REST APIs and redirects, so reserved characters do not change meaning.
