Extract text from Certificate archives (PFX)
To convert PFX Certificates to another format, you need Microsoft Management Console or other Encoded software.
To convert other file formats to the "PKCS#12 Certificate Archive" file type, you need software like Microsoft Management Console or a similar tool.
A .PFX file is a binary certificate archive following the PKCS#12 standard. System administrators use it to store a server certificate, intermediate certificates, and a private key in a single, encrypted package for secure transfer between servers.
You can manage these files natively using the Microsoft Management Console (MMC) on Windows systems, or extract them using the open-source toolkit OpenSSL.
Users often need to convert .PFX files because many popular web servers, such as Apache or Nginx, do not support this combined format directly. The main disadvantage of .PFX is its binary, password-protected nature. You cannot open it in a standard text editor to check the expiration date or certificate details. It is highly secure but practically opaque without specialized command-line tools.
The best conversion targets are PEM, CER, CRT, or KEY files. Converting to PEM splits the archive into human-readable, Base64-encoded text blocks. You will need the original password to extract the private key. During extraction, the binary wrapper is lost, but the cryptographic data remains perfectly intact.
This file format is difficult to open or convert online due to its strict encryption and binary ASN.1 encoding. Often, only the original cryptographic software can properly read or export the sensitive data. If our analysis detects supported underlying or embedded public certificates, viewing or conversion may still be possible.
Convert.Guru analyzes your PFX file, detects the exact format, and lets you read the text inside.
Users also converted JPG, P12, PDF, PFXS, JPEG, PNG, CER, PFXT, PXF, CRT, PEM, P7B and CERT files.
If you want to convert PFX file to PEM, CRT, P12, JKS, CER, SYS, DLL, EXE, DRV, VXD, 386 or COM, you can use Microsoft Management Console or similar software from the "Cryptographic Certificate 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 Microsoft Management Console or another comparable tool in the "Cryptographic Certificate Key Storage" 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 PFX converter.
