What is Base64 encoding used for?

Base64 is an encoding scheme that converts binary data (like images or encrypted payloads) into a sequence of 64 ASCII characters for safe transmission over text protocols such as HTTP, JSON, and MIME email.

What is URL-safe Base64?

URL-safe Base64 replaces the `+` character with `-` and the `/` character with `_`, and typically omits padding `=` characters so the string can be placed directly inside URL parameters.

Is Base64 considered encryption?

No. Base64 is purely a data representation format and offers no cryptographic security or secrecy. Anyone can decode a Base64 string instantly.
