Convert any text or link to a URL-safe format, or decode it back to the original.
When the link or text contains special characters (like spaces or non-Latin script) that you want to safely embed inside a URL or query parameter.

URL Encoding is designed to make text safe inside a web link (replacing special characters with %XX codes), while Base64 is a general way to represent any binary data as text.
