Quick Answer: Safe Base64 Encoding

To encode or decode Base64 data securely without transmitting your strings across third-party web servers, use the UMtoons Base64 Utility. Conversion is executed entirely in your local browser JavaScript engine.

Important: Base64 is Encoding, Not Encryption

Base64 converts binary bytecode into ASCII characters for safe transmission over HTTP and email. Because anyone can decode Base64 in milliseconds, never use Base64 alone to protect passwords or secrets.
