SignedDocs

SignedDocs is a web-based tool that helps users open and understand digitally signed documents in various formats (.p7m, .p7s, .tsd, .zfo, .es3, .xades, .asice) without needing specialized software. The platform supports documents from multiple countries including Italy, Germany, Hungary, Poland, Czechia, and Ukraine. Users can sign in with a free Google account to preview documents and view signer details directly in their browser without uploading files to servers.

Key features include automatic file format detection, document preview capabilities, signer identification, and support for nested file formats (like .pdf.p7m and .xml.p7m). The tool extracts and displays the contents of digitally signed packages, timestamps, and encrypted documents. It's designed for businesses, government employees, and individuals who receive official documents, supplier invoices, and PEC emails in signed formats.

The service offers a free tier for previewing documents and viewing signer information, with paid options for downloading extracted documents and PDF conversions. All file processing happens client-side in the browser, ensuring privacy and security.
