About URL Encoding

URL encoding converts characters that are not allowed in a URL into a format that is acceptable. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

There are two main JavaScript functions for URL encoding:

  • encodeURIComponent(): Encodes all characters except: A-Z a-z 0-9 - _ . ! ~ * ' ( )
  • encodeURI(): Encodes special characters except those that are part of a URI's structure (like :, /, ?, #)

For most cases, especially when encoding URL parameters, encodeURIComponent() is recommended.
