Cisdem PDF Password Remover is a small Mac utility for a frustrating moment: a PDF you own asks for a password before it will open, copy or print, and the password is lost or was set long ago. The app removes open and permission passwords from your files and saves unlocked copies, so you can read, edit and print your own documents again without rebuilding them from scratch.

Key Features

• Removes open passwords when the correct password is provided
• Lifts owner restrictions that block copying, editing and printing
• Batch processing for unlocking several PDF files in one run
• Keeps the original layout, text, images and links in the saved copies
• Simple drag and drop window with no technical steps to learn

How to Download

1. Open the official product page and use Download from the official site to get the Mac version.
2. Open the downloaded file and move the app into your Applications folder.
3. Launch the app, add a PDF you own, and save the unlocked copy.

System Requirements

The app needs macOS 10.15 or later. Version 5.4.0 added native support for Apple silicon, and it also runs on Intel Macs. It works on local files and needs no internet connection while processing.

FAQs

Is it legal to remove a PDF password?

Use this tool only on files you own or have clear permission to open. Removing passwords from other peoples protected documents is not appropriate.

Will the unlocked copy look the same?

Yes. The app saves a copy with the same content and layout, and the 5.4.0 release fixed links that could break after unlocking.

What if a file uses strong AES encryption?

Some strongly encrypted files cannot be processed. The Cisdem FAQ states that AES protected PDFs are not supported by the current version.
