Choose the Right App for Your Needs
Select apps based on your primary use case: basic viewing (free apps), professional editing (premium apps), or enterprise workflows (subscription services). Consider cross-platform needs if using multiple devices.
Configure Cloud Storage Integration
Connect your PDF app to cloud services (Google Drive, Dropbox, OneDrive, iCloud). This enables seamless document access across devices and automatic backup of annotated files.
Set Up Organizational Structure
Create folders by project, client, or document type. Use consistent naming conventions. Many apps offer tagging systems for better organization across large document collections.
Configure Security Settings
Enable app locking (Face ID, fingerprint, PIN). Set automatic timeout periods. Configure encryption for sensitive documents. Review app permissions regularly.
Optimize for Your Workflow
Create custom annotation presets, set default save locations, configure sharing shortcuts, and set up automation (like automatically backing up signed documents).
