Base64 Encode/Decode

Base64 encoding converts binary data into an ASCII string format using a set of 64 characters. It is widely used for embedding images in HTML/CSS, encoding email attachments via MIME, and transmitting data in URLs or JSON payloads. This tool handles full UTF-8 text correctly, ensuring multi-byte characters like emojis and accented letters are preserved during encoding and decoding.
