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 image data directly in HTML, CSS, or JSON files without requiring a separate file.

Key benefits of Base64 encoding:

  • Eliminates additional HTTP requests for small images
  • Useful for embedding images in CSS, HTML, SVG, or JSON
  • Simplifies data transfer when binary data can't be directly transmitted
  • Ensures data integrity during transmission
  • Works well for small icons, logos, and simple graphics

However, Base64 encoding increases file size by approximately 33%, so it's best used for small images (under 10KB) to avoid performance issues. For larger images, traditional image references are usually more efficient.
