About Base64 encoding

Base64 represents binary or text data using 64 printable ASCII characters, making it safe to embed in JSON, URLs, emails, or config files. This tool uses your browser's built-in TextEncoder and btoa/atob APIs, so it correctly handles Unicode text and nothing is sent to a server.
