PDF Encrypt Assisant vs QuickRoom3D

PDF files often contain important information such as contracts, invoices, resumes, or study materials. PDF Encryption Assistant is designed to protect your PDF files simply, quickly, and securely. It supports both single file and batch encryption, adding an extra layer of protection for your privacy. Key Features First, Single and Batch File Encryption. Select one or multiple PDF files and add password protection with one tap. Batch processing is completed in one go, and encrypted files are automatically generated as new PDF files without affecting the original files. Second, Show or Hide Password While Typing. Tap the eye icon while entering your password to show or hide the characters. This helps you confirm that you have typed the password correctly, avoiding the situation where you cannot open the file after encryption due to a typing mistake. Third, Safe Storage of Original Files. The newly encrypted files coexist with the original files. You can choose whether to keep the original unencrypted files. Fourth, Simple and Streamlined Workflow. No account registration required, no internet connection needed. All operations are performed entirely on your device. The app does not collect any file content or upload anything to any server. Fifth, Suitable for Multiple Scenarios. Including work documents such as contracts and quotes, study materials such as papers and exam answers, personal files such as ID scans and bank statements, and family sharing such as budgets and itineraries. Privacy and Security Statement All operations are completed solely on your iOS device. Files are never uploaded to any server. This app does not record your passwords, does not use any tracking or analytics tools, and only requests necessary file reading and saving permissions. Who This App Is For Professionals who want to protect work documents from being viewed without permission, teachers and students who want to encrypt study materials and answer keys, people who frequently handle contracts or financial documents, and anyone who values information security and wants an easy way to encrypt PDF files. Why Choose This App A simple PDF encryption tool that truly supports batch encryption rather than just changing file extensions. It also allows you to show or hide your password while typing. The interface is clean and beginner-friendly. Encryption is just three steps away: select files, enter a password, and start encrypting. Notes Encrypted PDFs can be opened with common PDF readers such as Adobe Acrobat or the system's built-in Preview by entering the password. Please remember your password, as this app cannot and will not recover it for you. — Privacy Policy please visit: https://docs.qq.com/doc/DREt1SXJkbG9JYUFT * **Terms of use (EULA)： * https://docs.qq.com/doc/DREdKR2ZwYUJaa1hr * **Terms of apple please visit: * https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
