Files with the .p7m extension are cryptographic containers that wrap an original document (such as a PDF file or an XML structured file) inside a CAdES or PKCS#7 digital signature envelope. Opening a .p7m file requires a specialized reader that can decode the cryptographic container and extract the underlying file.
P7M Viewer & Reader provides a native solution for opening P7M files directly on iPhone, iPad, and Mac. Unlike online converters that require uploading sensitive documents to third-party web servers, P7M Viewer & Reader processes every file locally on your device, ensuring complete privacy and high performance.
The app seamlessly handles P7M files containing embedded PDF documents or XML electronic invoices. With a single tap, you can inspect digital signature details, verify certificate information, and extract the underlying PDF or XML file directly to your local storage.
Additional capabilities include batch unarchiving of ZIP files containing multiple P7M files, opening .p7s and .p7c signature attachments, and visually rendering XML invoice data into clean, readable PDF views — all without requiring an active internet connection.

Frequently asked questions about P7M files.
What is a P7M file?
A .p7m file is a cryptographic container (PKCS#7 / CMS) that encloses an original document (such as a PDF or XML file) along with a CAdES digital signature.
How do I open a P7M file on iPhone, iPad, or Mac?
P7M Viewer & Reader allows you to open .p7m files directly on your Apple device and extract the enclosed PDF or XML file instantly.
Can I extract a PDF from a P7M file?
Yes. The app extracts the native PDF file wrapped inside the P7M container so you can save and view it separately.
Does it work without an internet connection?
Yes. P7M Viewer & Reader operates 100% offline on your device, ensuring complete privacy with zero cloud uploads.
Which file extensions are supported?
The app supports .p7m, .xml.p7m, .pdf.p7m, .p7s, .p7c, and ZIP archives containing P7M files.
