Anti-Screenshot Protection

Introduction

In today's digital landscape, protecting sensitive web content from unauthorized copying is crucial. One of the most effective ways to prevent content theft is through Anti-Screenshot Protection, a key feature of Web Code Protector.

Why Anti-Screenshot Protection?

This security measure ensures that users cannot easily capture or distribute screenshots of protected content, making it ideal for:

Premium digital products
Confidential business documents
Licensed media and content
Secure online examinations

How Anti-Screenshot Protection Works

Web Code Protector employs multiple techniques to prevent users from capturing screenshots or screen recordings:

1. Auto-Blur Effect

When a user attempts to take a screenshot (e.g., by switching windows or using keyboard shortcuts), the content automatically blurs:

function toBlur() {
}

// Trigger event
document.onmouseleave = toBlur;

Trigger Event:

onblur - Blurs when window loses focus

2. Disabling Print Screen & Shortcuts

Blocks screenshot keyboard shortcuts (PrtScn, Alt+PrtScn, Win+Shift+S):

// Block all keyboard inputs
function blockAllKeys(e) {
    if (e.key === 'PrintScreen' || e.keyCode === 44) return;
    e.preventDefault();
    return false;
}

Key Features:

Blocks all keyboard events when enabled
Shows warning modal on screenshot attempt
Clears clipboard contents

3. Right-Click & Drag Prevention

Blocks alternative screenshot methods:

// Disable right-click
document.addEventListener('contextmenu', (e) => {
    e.preventDefault();
});

// Disable text selection
document.addEventListener('selectstart', (e) => {
    e.preventDefault();
});

// Disable drag/drop
document.addEventListener('dragstart', (e) => {
    e.preventDefault();
});

Protected Actions:

Right-click context menus
Text selection
Drag-and-drop operations
Developer tools access

Frequently Asked Questions

Can users bypass the screenshot protection?

While no client-side solution is 100% foolproof, Web Code Protector makes it extremely difficult for average users to capture screenshots. It effectively prevents casual copying and raises the barrier significantly against content theft.

Does it work on mobile devices?

The protection works on mobile browsers but has limitations due to OS-level screenshot controls. The blur effect will activate when the app loses focus, but native screenshot gestures may still work.

Can I customize the blur intensity?

Yes! You can adjust the CSS blur filter values in the protection settings to make content slightly visible or completely obscured when protection triggers.
