What is Base64?

Base64 is an encoding method that converts binary data into ASCII text. This allows the data to be sent safely through systems that only support text.

Base64 is used for, among other things:

• API requests
• JSON and XML data
• email attachments
• tokens and authentication

Encode vs. decode

• Encode: converts regular text to Base64
• Decode: converts Base64 back to readable text

Please note: Base64 is not encryption, but an encoding method.

• Debugging API responses
• Checking tokens
• Processing binary data
• Web development and scripting
