URL Encoder & Decoder

The URL Encoder and Decoder percent-encodes special characters in URLs and query parameters according to RFC 3986, and decodes percent-encoded URLs back into human-readable strings. It is the tool you reach for when a link contains spaces, symbols or non-English characters that would otherwise break, and when you receive an encoded link that you want to read or inspect.

To use it, paste the URL or parameter value, choose encode or decode, and copy the result. When building links, encode each query parameter value separately rather than encoding a whole URL, so the separators between parameters stay intact. When decoding, read the result carefully to confirm it points where you expect before you click or share it.

The most common mistake is double encoding, where an already encoded value gets encoded again and percent signs turn into %25. If a link looks wrong after encoding, check whether the input was already encoded and start from the plain version instead. Also remember that different parts of a URL have different rules, so a value that is safe in a path may still need encoding in a query string.

One honest limitation: the tool encodes characters only. It does not check whether the resulting link works, whether the target page exists, or whether the destination is safe, so an encoded link is not a verified link.
