⚡Base64 Encoding Tips

  • • Base64 encoding increases file size by approximately 33%
  • • Best for small images like icons, logos, or placeholders
  • • Data URLs eliminate an extra HTTP request but increase HTML/CSS size
  • • Use 'Copy Data Only' when you need just the base64 string without the prefix
