Base64 Encoder / Decoder – Encode or Decode Text

What is Base64 used for?

Base64 is a text-based encoding format often used when binary data needs to travel through systems that expect plain text. Developers see it in APIs, tokens, email attachments, and embedded data. This tool lets you quickly encode readable text into Base64 or decode Base64 back into text. It is useful for testing, debugging, and learning how data is being transmitted.
