What Is Base64 Encoding?
Base64 is a text-based encoding format that represents binary or raw data using a limited set of ASCII characters. It is often used when data needs to travel through systems that handle text more safely than binary.
Why Base64 is used
Developers use Base64 in APIs, email attachments, tokens, data URLs, and embedded assets because it converts bytes into a text-friendly representation that is easier to transport between systems.
Encoding vs encryption
Base64 is not encryption. It only changes the representation of data, not its secrecy. Anyone can decode Base64 if they have the encoded string.
Common use cases
Common examples include passing files through JSON APIs, embedding images in HTML or CSS, transforming credentials for protocol headers, and moving structured content between services.
