Looking to open a .p7m file online? You do not need to download or install anything. This guide shows how to open any signed .p7m file directly in your browser, free of charge.
Open .p7m online in three steps
1. Open the P7M Viewer online tool.
2. Drop your .p7m file into the upload box.
3. View or download the original document — done.
Because it runs entirely online, it works the same on Windows, macOS, Linux, Android and iPhone.
Why open .p7m files online instead of with software?
Desktop signature programs are large, often paid, and tied to one operating system. Opening .p7m online is:
- Free for single files
- Instant — no setup
- Universal — any device with a browser
- Private — files are deleted automatically after processing
What kinds of documents are inside .p7m files?
Most .p7m files you receive contain a PDF or an XML electronic invoice, but they can also hold Word documents, images or plain text. P7M Viewer identifies the inner format and hands you the correct file.
See who signed the file
Beyond extracting the document, opening a .p7m file online with P7M Viewer reveals the signer's name and the signing date, so you know the file is genuine before you trust it.
Do more: batch and conversion
If you regularly receive many signed files, you can open dozens of .p7m files at once and download them all in a single ZIP. You can also convert your own PDF, Word, XML or UDF documents into .p7m when you need to send signed files yourself.
