A Major Update for Document Security and Content Protection
Today, VeryPDF Reader for Windows receives a major security-focused update:
it now supports complete screenshot blocking on the Windows platform.
This new feature is designed to prevent any form of screen capture, whether triggered by keyboard shortcuts, third-party screenshot tools, or even during video conferencing and screen sharing sessions. When enabled, protected PDF content cannot be captured, recorded, or leaked, even by advanced or commonly used screen capture software.
This update significantly strengthens VeryPDF Reader’s position as a secure PDF viewing solution for sensitive, confidential, or copyrighted documents.
What Does “Completely Blocking Screenshots” Mean?
Unlike traditional approaches that only block basic shortcuts such as PrintScreen, VeryPDF Reader now prevents all common screenshot techniques, including:
- Keyboard-based screen capture
- Third-party screenshot utilities
- Background capture services
- Screen capture during video meetings
When screenshot protection is enabled, any attempt to capture the document results in only a black rectangle being captured instead of the actual PDF content.
Screenshot Tools That Are Blocked
VeryPDF Reader’s new protection mechanism blocks virtually all popular screenshot tools on Windows, including (but not limited to):
Built-in Windows Capture Methods
- PrintScreen
- Alt + PrintScreen
- Win + Shift + S (Snipping Tool)
- Windows Snipping Tool
- Windows Game Bar capture
Popular Third-Party Screenshot Software
- Greenshot
- Snagit
- Lightshot
- ShareX
- PicPick
- FastStone Capture
- Gyazo
- Screenpresso
- Nimbus Screenshot
- Monosnap
Even when these tools are actively running in the background, they cannot capture protected content displayed inside VeryPDF Reader.
Screenshot Blocking During Video Conferences
A particularly important aspect of this update is its effectiveness during video conferencing and screen sharing.
When a protected PDF is opened in VeryPDF Reader:
- Screen sharing in video meetings shows only a black rectangle
- The actual PDF content is not visible to remote participants
- Recording the meeting does not capture the protected content
Video Meeting Software Affected
- Zoom
- Microsoft Teams
- Google Meet
- Webex
- Skype
- Slack screen sharing
- Tencent Meeting / Voov Meeting
This ensures that confidential documents remain protected, even in collaborative or remote work environments.
How It Works (High-Level Overview)
VeryPDF Reader uses advanced Windows-level protection mechanisms, including:
- Secure window rendering
- Low-level system interception
- Real-time detection of capture attempts
- Automatic content masking when risk is detected
This approach goes far beyond traditional PDF password protection or watermarking and operates at the operating system level, making it extremely difficult for third-party software to bypass.
User Experience: Secure but Seamless
Security does not come at the cost of usability.
- The feature is disabled by default
- Users can enable it through Advanced Settings
- When triggered, a clear message is displayed:
