Click the "Select File" button above, and choose your P7B file.
You’ll see a preview, if available.

Convert P7B to another file type
To convert your P7B file to another format, you need OpenSSL or other System software.
Convert a file to P7B
To convert other file formats to the "PKCS #7 Certificate Container" file type, you need software like OpenSSL or a similar tool.
About P7B files
The .P7B file is a security container based on the PKCS #7 Cryptographic Message Syntax Standard, primarily used to exchange public keys and certificate chains without including sensitive private keys. While widely supported by Microsoft Windows Server and Java environments (such as Tomcat), .P7B files create significant friction for administrators deploying to Linux-based web servers like Nginx or Apache HTTP Server, which typically require PEM or CRT formats. A common frustration arises when users attempt to install an SSL certificate on IIS and realize the .P7B file lacks the private key required for a complete handshake, necessitating a conversion or merge process. To make these files usable across different platforms, users often convert them to PEM (for Linux servers), extract individual CER files, or merge them with a private key to generate a PFX or P12 container for Windows/Azure deployment.
Convert.Guru analyzes your P7B file, detects the exact format, and lets you read the text inside.
If you want to convert P7B file to PEM, PFX, CER, CRT, P12, JKS, HTML, HTM, CSS, JS, PHP or ASP, you can use OpenSSL or similar software from the "Digital Certificate Storage" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to P7B, try OpenSSL or another comparable tool in the "Digital Certificate Storage" category.
The P7B Converter Story
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 P7B converter.
