What is Base64 Encoding?
Base64 is a encoding scheme that converts binary data into ASCII text format. It's commonly used to encode data for transmission over media that only support text, like URLs or emails.

Important Note
Base64 is encoding, not encryption. It provides no security - anyone can decode Base64. Don't use it to hide sensitive data!
