Is it possible to edit a secured PDF? Sure! In this article, we’ll explain how to remove security from a PDF to edit it.

It can occasionally be helpful to restrict access to a PDF for certain features, such as editing or printing, especially if we’re talking about important documents that shouldn’t be modified. To do this, we set passwords to protect the file. But what if you need to make changes to a password-protected file? With Smallpdf, unlocking your file for editing is easy. Our tools help you to access, edit, and print password-protected PDFs by removing their encryption.

A secured PDF document should only be edited by its author. Make sure you have the rights to remove the protection on your file before starting.
