This free in-browser tool securely converts your .cer/.crt file to .pfx (PKCS#12/.p12) format, with your sensitive files never leaving the web client.
If you want to convert these certificate files directly on your server, use the OpenSSL or Bash commands further down the page.
Use the following command options to convert your crt e file(s) to .pfx format. These commands work in OpenSSL and Bash (Linux/Unix).
Replace the placeholder values with your actual filenames and input extensions. If you want to include the private key or CA chain certificates, select those options to generate an updated command.
