PFX / PKCS#12 to PEM Converter
Extract certificates and the private key from a PFX (PKCS#12) container into separate PEM files, in your browser. Outputs the cert chain as one .pem and the private key as a .key. Like the reverse direction, the entire conversion runs locally — your private key stays on your machine.
How to use
- Drop your .pfx / .p12 file.
- Enter the export password.
- Click Convert. The PFX is decrypted in your browser and split into a .pem (cert chain) and a .key (private key).
- Both files are offered for download.
FAQ
What if I don't know the PFX password?
You can't decrypt it without the password. The PFX format is designed so passwords are required — there's no client-side workaround. Try common patterns or contact whoever generated the file.
Is the private key safe?
Yes. node-forge runs in pure JavaScript inside your browser. Open DevTools Network tab — no outbound traffic. The key only exists in your tab's memory and the .key file you download.
Is this really free?
Yes. No signup, no quota, no upgrade tier. The conversion runs on your machine, so it costs us nothing to host.
