What is Base64 Encoding?

Base64 is an encoding method that represents binary data using a limited set of ASCII characters. It is commonly used when binary data needs to be transported through text-based systems such as JSON, email, HTML, and APIs.

This encoder processes your text directly in your browser. Your input is not uploaded to a server.
