Frequently asked questions
What is Base64?
Base64 is an encoding method that transforms binary data into an ASCII character sequence, making it safe for transmission over systems that only support plain text (like emails or JSON payloads).
Is Base64 encryption?
No. Base64 is only an encoding format. It does not use passwords or protection algorithms. Never use Base64 to hide confidential information without encrypting it first.
