Certificate converter

Conversion runs inside PHP using its OpenSSL extension. No shell access or OpenSSL command-line binary is required. Files are processed in a private temporary workspace.

Maximum upload size: 10.0 MB. P7B contains certificates only; private keys are never included.

Before converting

A certificate file does not necessarily contain its private key. To create a PFX, you must provide the matching private key.

Private-key safety

Uploaded private keys are processed in a private temporary directory and deleted after download or cleanup. Avoid uploading high-assurance production keys to shared hosting.
