As the author of a document, you can certify it to control what can and cannot be done to the content while retaining the certified status. If changes occur to the document that you have not permitted, then the document is invalidated and the certificate is revoked.
Note: PDF files can be certified only once, but if permissions allow, can be digitally signed many times. This is the benefit of certifying the files you author, rather than signing it.
Note: When you share certified PDFs, the other users' PDF viewer must support the functionality for certification and signatures to work correctly.
1. Open Nitro Pro > click the Protect tab > Certify.
2. On the Certify Profile Wizard, choose the actions you want to permit from the Permitted actions list:
- Disallow any changes - Disables all tools that can be used to change a file, such as editing, commenting, form filling and signing. If any change is made to the document after certification, its certificate becomes invalid.
- Only allow form fill-in actions - Disables all tools that can be used to change a file, except for the form filling and signing tools. An example of when you would use this is when you want to collect information with an official form that requires people to enter information, but does not allow them to change the form you designed.
- Only allow commenting and form fill-in actions - Disables all tools that can be used to change a file, except for the form filling, signing, and commenting tools. An example of when you would use this is when reviewing a contract that may require signatures and comments during the reviewing stage.
3. Select a digital ID to certify with, and choose whether or not to make the certificate visible and click Next.
4. If you chose to make the certificate visible, click on the page where you would like it to appear.
5. On the Certify Document dialog, do the following:
- Select a reason for signing the file from the Reason for signing document list, or enter your own reason
- Choose to save the certification to the current document or save as a new document.
- Specify the appearance for the certificate.
6. Click Finish.

Nitro Pro has improved the experience of digitally signing and locking a PDF document. Nitro Pro will now display the time at which the document was locked after signing in the Audit Trail.
Once you are ready to sign, you can either click on the area you want to sign, or you can click-and-drag the mouse to create the size you want for your Signature:
