SignedDocs

SignedDocs is a web-based tool that helps users open and understand digitally signed document formats they cannot normally access. Simply drop your file (.p7m, .p7s, .tsd, .zfo, .es3, etc.) into the browser and SignedDocs identifies the format, extracts the contents, and displays the document and signer details without uploading your file to any server.

The tool supports multiple European digital signature standards used in Italy, Germany, Hungary, Czech Republic, Poland, and Ukraine. It's designed for individuals and businesses who receive official documents, supplier invoices, or messages via secure email systems (like PEC or data boxes) in formats their standard software cannot open.

SignedDocs offers a freemium model: create a free account with Google to preview documents and see signer information. Paid features include downloading extracted documents, converting to PDF, and printing capabilities. The file stays on your device during processing, ensuring privacy and security.
