Base64 Encoder / Decoder
Encode text to Base64 or decode Base64 back to text. Supports full UTF-8.
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used to embed images in HTML/CSS, encode email attachments (MIME), transmit data in URLs, and store binary data in JSON.
The encoding converts every 3 bytes of binary data into 4 ASCII characters from a set of 64 characters (A-Z, a-z, 0-9, +, /). The = character is used for padding when the input length isn't a multiple of 3.
