About Base64 encoding
Base64 is a binary-to-text encoding scheme that represents binary data using 64 ASCII characters. It's commonly used in email attachments, data URLs, and embedding small images directly in HTML or CSS. This tool encodes and decodes Base64 entirely client-side - none of your input is sent to a server.
