What is URL encoding?

URL encoding, also called percent-encoding, converts characters that have a special meaning in a web address or are not allowed in a URL into a format that can be safely transmitted. An encoded character is usually represented by a percent sign followed by two hexadecimal digits. For example, a space is commonly encoded as %20.

When should you encode or decode a URL?

Use URL encoding when text contains spaces or reserved characters and needs to be included in a URL component, such as a query parameter. Decode percent-encoded text when you need to read or inspect a URL value.

Tip: Encode individual URL components or parameter values, not an entire web address that already contains structural characters such as ?, & and =.
