Frequently Asked Questions (FAQ)
What is the difference between URL encoding and Base64?
URL encoding replaces unsafe ASCII characters (like spaces or special punctuation symbols) with a % followed by two hexadecimal digits so they can safely pass through web links. Base64 translates entire blocks of data into a strict alphanumeric alphabet.
