Add a visual signature

Sign your final PDF with a certificate
Use your own password-protected RSA signing certificate to add a cryptographic signature to a final PDF. This is separate from drawing a visual signature.
Open certificate signing →How it works
- Finish editing and choose an unsigned PDF up to 20 MB.
- Choose your RSA .p12 or .pfx certificate up to 1 MB, enter its password, and confirm that you are authorized to use it.
- Sign locally, save the result, and check the signature and certificate trust in your PDF reader. Do not edit the signed export.
Before you start
Certificate trust depends on its issuer and the recipient’s PDF reader. No trusted timestamp, revocation check, long-term validation or qualified-signature service is included. Existing signatures are not supported. The certificate, private key and password are used in this browser.
