❓FAQ

Q: What is Base64 encoding?

A: Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data in emails, URLs, and web applications.

Q: When should I use Base64 encoding?

A: Base64 is useful when you need to transmit binary data over text-based protocols, embed images in HTML/CSS, or store complex data in formats that only support text.
