P7M Extractor unwraps CAdES (.p7m) digitally signed files and saves the original document, byte for byte, next to the signed one. The format is used across Italy for signed contracts, drawings, PEC attachments and electronic invoices.
Drag and drop files or whole folders, or double-click a .p7m; every file is queued in a single window with its extraction progress. Nested signatures, binary, base64 and PEM containers and BER streaming are supported. English and Italian interface, light and dark theme.
The tool extracts the signed content; it does not validate certificates or the legal value of the signature.
