About Base64 Images

Base64 encoding converts images into text format that can be embedded directly in HTML, CSS, or JSON. This eliminates the need for separate image files and reduces HTTP requests.

Advantages

  • No additional HTTP requests - faster page load
  • Perfect for small icons and logos
  • Works well in email templates
  • Self-contained HTML files

Disadvantages

  • Increases file size by ~33%
  • Cannot be cached separately by browsers
  • Not suitable for large images
  • Makes code less readable

Best Practices

  • Use for small images (icons, bullets) under 10KB
  • Optimize images before converting
  • Consider SVG for vector graphics instead
  • Use traditional image files for photos
