What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. For images, this allows you to embed image data directly in HTML or CSS without external files.
When to Use Base64 Images
- Email templates: Embed images without hosting them separately
- Small icons: Reduce HTTP requests for tiny images
- Data URIs: Include images in JSON or configuration files
- Offline apps: Bundle images with your application
Limitations
- Base64 encoded images are ~33% larger than the original file
- Not suitable for large images (use external files instead)
- No browser caching benefits
Supported Formats
- PNG - Lossless compression, supports transparency
- JPG/JPEG - Lossy compression, smaller file sizes
