How To Edit a Secured PDF

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.

Compatibility

With Smallpdf, you don’t have to worry about compatibility. Our platform can unlock PDF files on Mac, Windows, iOS, Android, and even Linux. Those of you with a Smallpdf Pro subscription can use our desktop app to unlock and edit your PDFs completely offline.

How To Edit a Secured PDF File Offline

1. Download and install the Smallpdf Desktop App.
2. Click on the Unlock tool.
3. Add or drag your file(s) into the window.
4. Enter your password to unlock.
5. Click on the “Open” icon to start editing your file.

If you want to secure your document again after editing, use the Protect PDF tool to encrypt your PDF with a password of your choice. This encryption is so secure that your file can’t be opened or unlocked ever again without the password. Say goodbye to unauthorized access to your file’s content.
