How do I certify a PDF using my digital ID in Adobe Acrobat?

Open your PDF in Acrobat. Check for other signatures; remove them if needed. Go to the digital signature tools and choose to certify. Select your digital ID and place the signature. Save your certified PDF.

What is the difference between certifying a PDF and signing a PDF?

Certifying a PDF Signing a PDF. Applies a certificate signature and marks the PDF as official. Adds a personal digital signature to show who signed. Only possible if there are no other signatures. Can be done by many people after certification. Shows a ribbon icon and protects the document from changes. Shows who signed but does not always protect the whole document.

If my Final EIS PDF already has a signature, can I still certify it?

No, you cannot certify a PDF that already has signatures. You must remove all signatures before certifying. Always check for existing signatures before starting.

Why would I use the PDF Electronic Seal API instead of certifying in Acrobat?

The API is helpful if you need to certify many PDFs automatically. It can use an organization’s certificate and seal image for official documents. Using the API saves time and avoids manual steps for large batches.
