A simple yet powerful client-side tool for encoding plain text into Base64 and decoding Base64 strings back to their original form. This tool is essential for developers working with data transmission, web tokens, or any scenario where binary data needs to be safely represented as text. The entire process happens in your browser, ensuring your data remains private and secure. Features include automatic detection of input type (plain text vs. Base64), one-click copy functionality, and a clear button to reset the fields.
