About URL Encoding
URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. URL encoding is used when placing text in a query string to avoid it being interpreted as URL syntax, and also to handle the characters that cannot be used in a URL.
Characters that are not alphanumeric or are not one of - _ . ! ~ * ' ( ) should be encoded. The encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits corresponding to the character's value in the ISO-Latin character set.
This tool provides a simple way to encode and decode text for use in URLs. All processing happens directly in your browser - no data is sent to our servers.
