About this tool

URL encoding (also called percent-encoding) replaces special characters in a URL with a percent sign followed by their hexadecimal code. This is required because URLs can only contain certain ASCII characters. Characters like spaces, ampersands, and equals signs must be encoded to be safely included in query strings or URLs. This tool encodes or decodes any string for use in URLs.
