What is Base64 Embedding?

Base64 embedding allows you to include images directly in HTML, CSS, or other code without requiring separate image files. The image data is encoded as Base64 and embedded as a data URI, reducing HTTP requests and simplifying deployment.

Common Use Cases

Email Templates: Embed images in HTML emails to ensure they display without external dependencies.

Single-File Applications: Bundle small icons and logos into a single HTML file for easy distribution.

Offline Web Apps: Embed images so web applications work without network access.

CSS Sprites Alternative: Embed small UI icons directly in CSS to reduce HTTP requests.

Best Practices

Size Considerations: Base64 encoding increases file size by ~33%. Only embed small images (under 10KB) for optimal performance.

Caching: Embedded images can't be cached separately from the HTML/CSS file. Use external files for large or frequently updated images.

Browser Support: Data URIs are supported in all modern browsers, but very old browsers (IE7 and below) have limitations.

Privacy and Security

All image processing and code generation happens locally in your browser. Your images are never uploaded to any server. This ensures complete privacy for confidential or sensitive images.
