Encode text to Base64.

What Is a Base64 Encoder?

The Base64 Encoder converts plain text into Base64, a binary-to-text encoding scheme that represents binary data using 64 ASCII characters (A-Z, a-z, 0-9, +, and /). Base64 is widely used to safely embed binary data in text-based protocols such as email attachments, JSON payloads, and data URIs.

No. Base64 is an encoding, not encryption. Anyone can decode it instantly. It exists to make binary data safe for text-based systems, not to hide information.
