What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data (like images) in an ASCII string format. This allows you to embed images directly in HTML, CSS, or JSON without separate files.
When to Use Base64 Images
✅ Small images - Icons, logos under 10KB
✅ Reduce HTTP requests - Inline critical images
✅ Email templates - Embed images that display without external loading
✅ Single-file HTML - Create self-contained HTML files
❌ Large images - Base64 increases size by ~33%
❌ Frequently changing images - Cannot be cached separately
Usage Examples
HTML: <img src="data:image/png;base64,...">
CSS: background-image: url(data:image/png;base64,...);
JSON: {"image": "data:image/png;base64,..."}
