SignedDocs

SignedDocs is a web-based tool that helps users open and understand digitally signed document formats they cannot access elsewhere. The platform supports multiple European digital signature formats including .p7m, .p7s, .tsd, .zfo, .es3, and others commonly used in Italy, Germany, Hungary, Czechia, Poland, and Ukraine. Users can upload files directly in their browser without the files being stored on servers, maintaining privacy and security.

Key features include format identification, document preview, signer details extraction, and the ability to view contents of signed document packages. The free account provides document preview and signer information, while paid tiers unlock full document downloads and PDF conversion capabilities. Each supported format has dedicated documentation explaining its use cases and origin country.

SignedDocs is ideal for businesses and individuals receiving signed documents from international suppliers, government agencies, and official communications who need quick access and verification without specialized software installation.
