Signed .p7m files often arrive when you are away from your computer. The good news: you can open a .p7m file on your phone in seconds, whether you use Android or iPhone.
Open a .p7m file on your phone in three steps
1. Save the .p7m file to your phone (from email, WhatsApp or your Files app).
2. Open the P7M Viewer tool — the website works on every phone, and Android has a free app.
3. Upload the file and view or download the original document.
Android
On Android you can use the free P7M Viewer app for one-tap opening and sharing, or simply use the website in Chrome or Samsung Internet. Both extract the document instantly.
iPhone and iPad
On iOS, open the P7M Viewer website in Safari, tap Choose file, pick your .p7m file from Files or iCloud, and read the document. No app installation is required.
Reading signed invoices on mobile
The most common .p7m files on phones are electronic invoices in `.xml.p7m` form. P7M Viewer turns them back into a clean, readable document so you can check the details on the go.
Tips for a smooth experience
- Save the attachment before uploading — do not try to open it directly from the mail preview.
- Do not rename the file to .pdf; extract it properly instead.
- For frequent use on Android, the app is faster than the browser.
