ZFO Soubor

ZFO Soubor is a web-based tool for opening and processing ZFO files from the Czech digital mailbox (datová schránka) directly in your browser. The service allows users to preview file contents, extract individual documents, and convert them to readable PDF format or download them as ZIP archives without requiring any software installation.

Key features include free preview of file metadata and signature information, the ability to download individual documents or entire message packages, and secure client-side processing where files never leave your device. The tool works across desktop and mobile devices and provides an alternative to specialized software like 602XML Filler, making it accessible for users who need to occasionally access their digital mailbox documents.

The service is designed for Czech citizens and businesses who use the official digital mailbox system and need a quick, no-install solution to read and extract documents from ZFO containers.
