💡 About Base64 Encoding
  • What is Base64? A binary-to-text encoding that represents binary data in ASCII string format.
  • Size Increase: Base64 encoding increases file size by approximately 33%.
  • Data URI: Format is data:[mime-type];base64,[encoded-data]
  • Browser Support: All modern browsers support Base64 images.
  • Best For: Small images (icons, logos) under 10KB. For larger images, use regular URLs.
⚠️ Considerations
  • Base64 images are not cached by browsers like regular images
  • Increases HTML/CSS file size
  • Best for small, frequently used images
  • Not recommended for images larger than 10-20KB
