What is Base64 encoding?

Base64 is a method of encoding binary data as ASCII text. It is commonly used to embed images in HTML or CSS, encode email attachments, and pass data safely through URLs and APIs.

Base64 encoded strings are about 33% larger than the original data. It is not encryption — anyone can decode a Base64 string — so do not use it to hide sensitive data.
