What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed images in HTML/CSS, encode email attachments (MIME), and pass data in URLs.

Is Base64 encryption?

No. Base64 is an encoding, not encryption. It does not provide any security. Anyone can decode Base64 back to the original data. Use it for data transport, not for hiding secrets.
