About Image to Data URL (Base64)

Image to Data URL converts a small image (favicon, icon, badge) into a base64 data URL you can embed directly in CSS or HTML — useful for inline styles, single-file demos, email templates, and avoiding extra HTTP requests for tiny assets. Note: data URLs are ~33% larger than the source bytes. Best for files under 10 KB. Larger images should stay as separate files.
