PFX / PKCS#12 Generator
Securely combine your PEM certificates and private key into a single PFX format entirely in your browser. No data is ever sent to a server.
What is a PFX/PKCS#12 file?
A PKCS#12 or PFX file is a single, encrypted archive that stores server certificates, any intermediate certificates, and a private key. It's commonly used in Microsoft Windows Server environments (IIS) and Azure for SSL deployment.
Why is this tool secure? (Client-Side Processing)
Handling private keys requires utmost security. This tool leverages Client-Side Processing meaning the entire PKCS#12 generation happens locally in your browser using JavaScript. Your private key and certificates are never transmitted over the network or saved on our servers.
When to use a CA Bundle?
Including a CA (Certificate Authority) Bundle or Intermediate Certificates ensures that the client's browser can trace the certificate chain back to a trusted root CA. If your certificate provider sent intermediate certificates, include them here to prevent "Untrusted Connection" errors.
