About Base64 Encoding

  • Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format.
  • It is commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text.
  • Common use cases include encoding email attachments, embedding image data within HTML/CSS/XML, and storing complex data in JSON.
  • All encoding and decoding is performed in your browser - your data never leaves your device.
  • The encoded output will be approximately 33% larger than the input.
