About Base64 Encoding

Standard Base64: Uses A-Z, a-z, 0-9, +, and / characters with = for padding. Commonly used for encoding binary data in email, JSON, and XML.

URL-safe Base64: Uses A-Z, a-z, 0-9, -, and _ characters without padding. Safe for use in URLs and file names where + and / would need escaping.

Use Cases: Encoding binary data for transmission, embedding images in HTML/CSS (data URLs), storing binary data in text formats, encoding authentication tokens.
