This document explains how to edit secured PDFs. (If you are looking for information on how to edit text or images in a PDF or more, click the appropriate link above.)
If a PDF document is secured, it is not supposed to be edited unless you are the author. Contact the author or the creator of the PDF document to edit it.
You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. You can remove security from a PDF if you have the document password. If the PDF is secured with a server-based security policy, only the policy author or a server administrator can change it. Contact the creator or the author of the PDF to get the password to edit the PDFs.
When you try to edit a password protected PDF, you get the following error.
Steps to remove password security
Your options vary depending on the type of password security attached to the document:
- If the document has a Document Open password, click OK to remove it from the document.
- If the document has a permissions password, type it in the Enter Password box and then click OK. Click OK again to confirm the action.
You can now edit the PDF.
Forgot the document or permissions password?
- If you are the owner of a PDF and don't remember the password required to open the PDF, you have to re-create the PDF. There is no way to recover the password in Acrobat DC.
- If you are the owner of a PDF and have forgotten the permissions password used to restrict certain features in the PDF, follow the workaround below to make the PDF editable.
Printing a file to PDF using the Adobe PDF printer flattens the file and removes interactive elements, such as bookmarks, hyperlinks, and buttons.
Certifying a document assures recipients that the document is authentic. If a PDF is signed using a digital ID or certificate, it’s locked to prevent changes to the document. Digital IDs or certificates used to sign PDFs are used for the commercial and legal purpose and are governed by laws in many countries.
When you try to edit a signed or certified PDF, you get the following error.
