File Handling and Data Privacy Policy

Last updated: April 2026

JustConvertPDF.com provides free online PDF conversion, compression, merging, and security tools. Because our tools handle your documents, we take your privacy and data security seriously. This policy explains how we handle files uploaded to our service.

How Our Tools Process Files

Our PDF tools process files directly in your web browser using client-side JavaScript technology. This means:

Your files are not uploaded to our servers. All processing happens locally on your device.
Your documents never leave your computer during conversion, compression, or merging operations.
We have no access to the content of your files at any time.
No file data is stored, cached, or retained after you close the browser tab.

No Data Collection from Files

We do not read, scan, analyze, index, or store the content of any documents you process using our tools. We do not use your documents to train AI models, improve our services, or for any purpose other than the specific conversion or operation you requested.

Browser-Based Processing

Because processing occurs in your browser, the speed and capability of our tools depends on your device hardware (processor speed and available memory). Very large files may process slowly or may exceed your device memory limits. This is a tradeoff we make to ensure your privacy — server-side processing would be faster but would require uploading your files.

What We Do Collect

Like most websites, we collect standard analytics data to understand how our site is used:

Page views and tool usage statistics (which tools are used, not what files are processed)
Browser type and device information
Referring website and general geographic location
We use cookies for analytics and to remember your preferences

This analytics data cannot be used to identify you personally or to access any documents you have processed.

Security Recommendations

While our tools process files locally for maximum privacy, we recommend the following best practices for handling sensitive documents:

Always use a secure, up-to-date browser when processing sensitive documents
Ensure your device has current antivirus and security software
Close the browser tab after completing your conversion to clear any temporary data from memory
For highly confidential documents (legal, medical, classified), consider using offline tools instead of any web-based service

Third-Party Services

We use Google Analytics for website traffic analysis and may display advertisements through Google AdSense. These third-party services may use cookies to serve relevant ads. See our Privacy Policy for full details on cookies and third-party data collection.
