About this certificate sign pdf tool

Your certificate and password stay in the browser. Adds a detached SHA-256 signature. Requires an unexpired RSA or EC certificate. No certificate issuance, trusted timestamp, revocation check or identity verification. Trust depends on your issuer and PDF viewer.

When to use this tool

Apply a SHA-256 certificate signature without uploading your key.

Get started in three steps

  1. Choose your PDF file from your device.
  2. Finish edits before signing. Subsequent changes can invalidate signatures.
  3. Select Sign on this device, review the result and download your file.

Before you download

Does PaperLumo issue a trusted certificate?

No. Supply your RSA or EC certificate. Trust depends on the issuer. No trusted timestamp, revocation check or identity verification is provided.

Where is my document processed?

Document processing runs in your browser. This tool does not upload your document for processing. Optional analytics measures page visits only after you allow it; it does not receive your document content. Read the privacy policy.

Next step: Sign PDF.
