Convert PFX to another file type
To convert your PFX file to another format, you need OpenSSL or other System software.
Convert a file to PFX
To convert other file formats to the "Security Certificate Archive" file type, you need software like OpenSSL or a similar tool.
About PFX files
A .pfx file (Personal Information Exchange) is a secure, password-protected container used to store cryptographic keys and certificates in a single binary file. It strictly follows the PKCS#12 standard and is critical for SSL/TLS implementations, code signing, and client authentication, bundling a private key with its corresponding X.509 certificate chain. While .pfx is the default format for Windows servers and Microsoft Azure, it presents significant compatibility hurdles for Linux-based infrastructure. Most open-source web servers like Apache HTTP Server and Nginx cannot use .pfx files directly; they require the certificates and keys to be extracted into unencrypted PEM, CRT, or KEY text formats. Furthermore, Java applications require conversion to the JKS (Java KeyStore) format. Handling .pfx files manually often involves complex command-line operations with OpenSSL, risking data loss or corruption if flags are misused.
Convert.Guru analyzes your PFX file, detects the exact format, and lets you read the text inside.
If you want to convert PFX file to PEM, CRT, P12, JKS, CER, SYS, DLL, EXE, DRV, VXD, 386 or COM, you can use OpenSSL or similar software from the "Cryptographic Key Storage" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to PFX, try OpenSSL or another comparable tool in the "Cryptographic Key Storage" category.
The PFX 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 PFX converter.
