FAQs

Why isn't the PDF displaying?

Ensure your browser has a built-in PDF viewer. Some browsers may block embedded PDFs. Try clicking 'Open in New Tab' instead.

Is my document secure?

Yes. All decoding happens locally in your browser. Your PDF data is never sent to any server.

Can I decode password-protected PDFs?

The tool will decode the file, but you'll need to enter the password in your browser's PDF viewer to view the content.
