    Frequently Asked Questions

    What is Base64 encoding?

    Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used for transmitting data over media designed to handle text, such as email or JSON.

    Why use Base64?

    Base64 encoding is used when you need to encode binary data for transmission over protocols that only support text data, such as embedding images in HTML/CSS, transmitting data in JSON, or handling authentication tokens.
