When should I use Base64-encoded images?

Best for small images (<10KB) like icons, logos, or inline graphics. For larger images, regular image files with proper caching are more efficient.

Will Base64 encoding increase file size?

Yes, Base64 encoding increases size by approximately 33%. However, embedding images can reduce HTTP requests, which may improve overall page load time for small images.
