Is Base64 a form of encryption?

No. Base64 is purely an encoding format for safe data transmission, not encryption. Anyone can decode a Base64 string instantly without any secret key.

Why are '=' characters added to the end of Base64 strings?

The '=' symbol is padding used when the length of the input data in bytes is not divisible by 3, ensuring the output aligns cleanly to 4-character blocks.

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary or text data in an ASCII string format using a radix-64 representation (A-Z, a-z, 0-9, +, /).

It was engineered to transmit arbitrary data across networks and protocols (such as MIME email or HTTP Data URLs) that were historically designed only to carry printable 7-bit ASCII text safely without corruption.

Encoding into Base64 increases the data footprint by approximately 33% because every 3 bytes (24 bits) of raw data are divided into four 6-bit chunks.
