Base64 Encoder & Decoder
Encode text to Base64 or decode Base64 strings back to readable text.
What is Base64?
Base64 is an encoding scheme that converts binary data into a text format using 64 ASCII characters (A-Z, a-z, 0-9, +, /). It's used to transmit binary data over text-based protocols like email (MIME), embed images in HTML/CSS (data URIs), and store binary data in JSON. Base64 increases data size by ~33%.
