Receiving a .p7m file on your phone and not being able to open it is a common situation. The good news is that you can open a .p7m file on your phone in just a few seconds, on both Android and iPhone. Here's how.
Why does my phone not open .p7m files
A .p7m file is a document (PDF, XML, Word) enclosed in a digital signature envelope (PKCS#7 / CAdES). The phone does not recognize this envelope and shows a file that does not open. It's not broken: you just need to extract the document.
Open a .p7m from your phone in 3 steps
1. Save the .p7m file on your phone (from email, WhatsApp or Files).
2. Open the P7M Viewer Open .p7m tool in your browser.
3. Tap Choose file, select the .p7m and view or download the document.
It works on any phone, without installing programs.
On Android
On Android you have two possibilities:
- Free P7M Viewer App: Install from Google Play and open or share .p7m files with one tap.
- Browser: use the site directly from Chrome or Samsung Internet.
On iPhone
On iPhone, open the site with Safari, tap Choose file, choose the .p7m from File or iCloud and read the document. No apps to install.
The file remains on the phone
With P7M Viewer the processing takes place in the phone's browser: the file is not uploaded to any server. Ideal for invoices and confidential documents.
