About Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed binary data in JSON, HTML, CSS, emails, and URLs.
This tool handles UTF-8 text encoding properly, so international characters, emojis, and special symbols are encoded and decoded correctly.
