What is Base64?
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), transmit binary data in JSON/XML, and store complex data in URLs or cookies. This tool encodes and decodes Base64 entirely in your browser with full UTF-8 support.
