About URL Encoding

Why Encode URLs?

URL encoding ensures that URLs can be transmitted safely over the internet. Special characters and non-ASCII characters need to be encoded to prevent misinterpretation.

Common Characters:

%20 or + → Space
%3A → Colon (:)
%2F → Forward slash (/)
%3F → Question mark (?)
%26 → Ampersand (&)

When to Use:

  • Building URLs with user input
  • Query parameter encoding
  • Form data submission
  • API calls with special characters
  • File paths with spaces

Standards:

URL encoding follows RFC 3986 standards, converting characters to UTF-8 bytes and representing each byte as a %XX sequence.
