Image Embedding Best Practices
1. File Size Considerations
Base64 encoding increases file sizes by approximately 33%. Keep inline images small (typically under 10KB) to prevent bloating stylesheets.
2. Caching Implications
Unlike external image files, inline Data URIs are cached as part of the HTML or CSS document, avoiding extra HTTP roundtrips for critical icons.
