Extract text from P7Z files
To convert your P7Z file to another format, you need Microsoft Outlook or other Encoded software.
To convert other file formats to the "S/MIME Compressed Data" file type, you need software like Microsoft Outlook or a similar tool.
A .p7z file is primarily associated with the S/MIME (Secure/Multipurpose Internet Mail Extensions) standard, specifically acting as a compressed container for email data. Users most frequently encounter this file as an attachment named smime.p7z when receiving digitally signed or encrypted emails in clients like Microsoft Outlook or generic webmail interfaces that do not natively support inline decompression of the message.
The technical reality of .p7z is that it wraps the actual email body and attachments (often in MIME format) inside a PKCS #7 CompressedData structure. A common issue for users is that while the underlying data is standard text or HTML, the .p7z wrapper renders it unreadable without specific software or an S/MIME-capable client. It is not an image or a simple document; it is an envelope. Consequently, you cannot simply 'open' it in a word processor. To access the contents - whether for legal discovery, archiving, or simple reading - you typically need to 'convert' the file by decoding the S/MIME layer and extracting the inner EML, TXT, or HTML payload. For long-term preservation, extracting the content and converting the final document to PDF/A is the recommended workflow to eliminate the dependency on email certificates and specific cryptographic libraries.
Convert.Guru analyzes your P7Z file, detects the exact format, and lets you read the text inside.
Users also converted P7S, SIG, BTW, PK, APB and 7 files.
If you want to convert P7Z file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use Microsoft Outlook or similar software from the "Compressed Email Message" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to P7Z, try Microsoft Outlook or another comparable tool in the "Compressed Email Message" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our P7Z converter.
