A P7M file is an encrypted mail message. Do you want to convert P7M to PDF or vice versa for some reason? If so, this post is what you need, in which MiniTool PDF Editor shows you how to do that.

What Is a P7M File?

The P7M file extension is associated with the S/MIME signature (Secure/Multipurpose Internet Mail Extension) file, which is a signature file that sends and receives secure information through an email client.

The P7M file format is a container format and the contents and the attachments of the encrypted email message are enveloped into the encrypted P7M file (SMIME.P7M file).

How to open a P7M file? In general, you can open P7M files using Outlook, but the private key must match the message's public key. This private key is static and does not change so that a user does not have to enter new information to open each P7M file they receive.

Besides, you can also use software like P7M Viewer to verify the key and then open the P7M files.

What Is a PDF File?

PDF is a file format developed by Adobe and has become very popular because it can present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.

Therefore, many official files like government documents, legal contracts, corporate agreements, regulations, news articles, academic papers, etc. almost use this file format to display, save, or share.

Besides, a PDF file can contain various contents including vector graphics, text, bitmap graphics, interactive elements, multimedia objects, etc.
