PEM to PPK Converter - Free Online

Drop any OpenSSH PEM private key and receive a PuTTY-ready PPK without touching the terminal.

Upload & convert

Choose your `.pem` file (or any RSA private key in PEM format) and convert it to a `.ppk` in one click.

Before you start

Keep conversions safe & tidy

Three quick reminders so the PuTTY key you generate here never leaks or surprises you in production.

01

Stick to supported key types

Use keys generated for RSA/Ed25519; encrypted PEMs require the same passphrase when PuTTY prompts.

02

Clean up shared devices

Close the tab or run a secure wipe after conversion if you are on a workstation that others can access.

03

Rotate secrets per environment

Regenerate keys whenever you convert credentials for a different environment so you never reuse access.
