Convert Image to Base64 for CSS and HTML

Encode images to Base64 data URIs for inline CSS, HTML emails, and small icons.

Quick answer

Base64 images embed directly in code, reducing HTTP requests. Use them only for small images because the encoded string is larger than the original file.

Privacy note

Keep the source file saved until the output is verified. Browser-local tools avoid uploads where possible, and heavy conversions use encrypted temporary processing only when the format requires it.
