Convert PEM to PFX
Bundle your Certificate, Private Key, and optional Intermediate CA Certificates into a single PKCS#12 (.pfx) file.
Step 1: Private Key
Provide the Private Key used to generate the original CSR.
Note: You can skip this if your ZIP file in Step 2 already contains the private key.
Step 2: Certificates (Auto-detect via ZIP)
Did you receive a ZIP file from your Certificate Authority (CA)? Drop it here and we will automatically sort the Primary and CA certificates!

How does the ZIP auto-detection work?
When you drop a ZIP file, the magic happens entirely within your browser:
- It unzips the file in your browser's memory.
- It scans all files for standard extensions (like
.crt, .pem, .key, .ca-bundle, .p7b) or filenames containing "bundle". - It reads the text of those files and uses a pattern matching algorithm (Regex) to extract any Private Keys and Certificates it finds, regardless of the filename.
- It uses the built-in WebAssembly crypto module to test every certificate against the Private Key until it finds the exact mathematical match (the Primary Certificate).
- All remaining certificates are assumed to be Intermediate CAs.
Security Note: All of this processing happens locally. Your private keys and certificates are never uploaded to our servers.
