Securely Encode or Decode URLs Instantly in Your Browser
URL encoding, officially known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are allowable in a URI are either reserved or unreserved. Reserved characters are those that have special meaning (like the slash / or the question mark ?), while unreserved characters have no such meaning.
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, URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
Encoding: You should encode a string when placing it inside a URL query parameter. For example, if you are passing a user's email address or a search query like "hello & world" in a URL, the ampersand (&) must be encoded to avoid breaking the URL structure.
Decoding: You decode a string when you want to read the actual content of a URL parameter. If you receive a URL like search?q=hello%20world, decoding it reveals the original query: "hello world".
%20%21%22%23%24%26encodeURIComponent logic, which encodes special characters including: , / ? : @ & = + $ #. This ensures the string is safe to include as a specific query parameter within a larger URL.Last Updated: [Current Date]
