SignedDocs

SignedDocs is a web-based tool that helps users open and understand digitally signed document formats that are difficult to access. The platform supports multiple international formats including .p7m, .p7s, .tsd, .zfo, .es3, and .xades files commonly used in Italy, Germany, Hungary, Czechia, Ukraine, and Poland. Users can drop their files directly into the browser where they are processed locally without uploading to servers.

Key features include file format identification, document preview, signer details display, and extraction of embedded files. The tool offers a free account tier that provides document preview and signer information, with paid options for full document downloads and PDF conversion. It's particularly suited for businesses and individuals receiving official documents, invoices, PEC emails, and government communications in various European digital signature formats.
