Are my PDF documents uploaded to any server?

No! The entire decoding and rendering process happens 100% locally in your browser using Blob URLs and HTML5 sandboxed iframes.

Does it support data:application/pdf;base64 prefixes?

Yes. The converter automatically detects and strips Data URI prefixes and extra whitespace from your Base64 input.
