Base64 Encoder/Decoder converts text to Base64 and decodes Base64 back into readable text. This is useful when testing APIs, inspecting encoded payloads, or working with systems that only accept text-safe data.
Base64 is a transport format, not a security feature. It is commonly used in tokens, payloads, and text-based transmission workflows, but it should never be treated as encryption.
Everything runs in the browser, which makes it convenient for quick debugging without exposing data to third-party services.
