About Base64 Image Encoding

What is Base64? Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed images directly in HTML, CSS, or JavaScript files.

Advantages:

  • Reduces HTTP requests by embedding images directly in code
  • Useful for small images and icons
  • Can be used in environments where external resources are restricted

Considerations:

  • Base64 encoded images are about 33% larger than the original binary
  • Not suitable for large images due to increased file size
  • Browser caching is less effective for embedded images
