SignedDocs

SignedDocs is a browser-based tool that helps users open and understand digitally signed document formats that are commonly difficult to access. The platform supports multiple European digital signature formats including .p7m, .p7s, .tsd, .zfo, .es3, and .xades files, which are commonly used for official documents, invoices, and PEC emails across Italy, Germany, Hungary, Czechia, Poland, and Ukraine.

Key features include file format identification and explanation, browser-based preview without uploading files to servers, signer details and verification, and the ability to extract documents from signed packages. Users can create a free account with Google to access document previews and signer information, while downloading extracted documents or PDF copies requires a paid plan.

SignedDocs is designed for businesses and individuals who regularly receive digitally signed documents from suppliers, government agencies, and official sources, particularly in European markets where digital signatures are legally mandated.
