How Do I Encode or Decode Image to Base64 Online?
Convert images to Base64 encoded strings for embedding in HTML/CSS.
Data URIs and inline images
Base64-encoded images can be embedded directly in HTML or CSS as data URIs, eliminating an HTTP request. This is ideal for small icons and logos (under 5KB) but increases HTML file size by ~33%. For larger images, regular file URLs with proper caching are more efficient.
