Encode

Upload an image and click Encode to generate Base64 string, Data URI, and developer code.

MIME validated server-side. SVG sanitized before encoding.

Large Data URI Warning
Base64 increases data size by ~33%. Large images encoded as Data URIs will significantly increase HTML/CSS file size and may slow page loads. Consider using a normal image URL for large assets.
Generated Output
