What is Base64? Base64 is a binary-to-text encoding scheme that represents binary data as ASCII text. Commonly used for embedding images in HTML/CSS, transmitting data over text-based protocols (email, JSON), and storing binary data in text formats. All processing happens in your browser � no data is sent to any server.
