URL Encoder & Decoder

URL Encoder/Decoder

Why Do URLs Need Encoding?

URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. For example, a space character is encoded as "%20".

Encode vs. Decode

  • Encode: Converts a string with special characters (like spaces, `&`, `?`) into a valid URL format that can be safely transmitted.
  • Decode: Converts a URL-encoded string back into its original, human-readable format.
