THE BASICS
What Is Base64 Encoding?
Base64 is a method of converting binary data into a text-based format using a set of 64 characters. It is commonly used to represent data in systems that support text-based communication.
Base64 encoding is frequently used in web development, API integrations, email attachments, data transmission and image data representation.
A Base64 Encoder converts text or supported data into a Base64 string, while a Base64 Decoder reverses the process to recover the original data.
