About Base64 Encoding

What is Base64:

  • Base64 is a method to represent arbitrary binary data using 64 characters. It's commonly used to encode and transmit binary data over media that are designed to handle textual data.

    • Use Cases:

    • Email attachment transmission
    • Embedding image data in web pages
    • API data transmission
    • Storing binary data in configuration files
    • URL-safe data transmission

    Important Notes:

    • Base64 encoded data is approximately 33% larger than the original
    • Base64 only contains A-Z, a-z, 0-9, +, / and = (for padding)
    • This tool supports UTF-8 encoded Chinese characters
