What is Base64?

Base64 is a way to encode binary data (like images) into text format using only ASCII characters.

This allows images to be embedded directly in HTML, CSS, or JSON without needing separate files.

Note: Base64 encoding increases file size by approximately 33%.

Use Cases

  • Embed small images directly in HTML/CSS
  • Include images in API responses
  • Store images in databases
  • Send images in JSON payloads
  • Create self-contained HTML documents
  • Email templates with embedded images

Best Practices

  • Only use Base64 for small images (icons, logos, thumbnails)
  • Large images should be served as separate files for better caching
  • Base64 images cannot be cached separately by browsers
  • Consider using SVG for icons instead of raster images
  • Optimize images before converting to reduce Base64 size
  • Use WebP format for better compression before encoding
