    Privacy Policy

    Last updated: February 2026

    🛡️ The Short Version

    Your files never leave your device. We don't collect, store, or transmit any of your data.

    1. Introduction

    OnlinePDFPro ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website at onlinepdfpro.com.

    2. File Processing

    All file processing occurs entirely in your web browser. When you use any of our tools:

    • Your files are never uploaded to our servers or any third-party servers
    • Files are processed using JavaScript that runs locally on your device
    • We have no access to your files or their contents
    • Processed files exist only in your browser's memory until you download them or close the tab

    3. Local Storage

    We use your browser's local storage to save:

    • Theme preference: Whether you prefer light or dark mode
    • Recently used tools: A list of tools you've recently accessed for convenience

    This data is stored locally on your device and is never transmitted to us.

    4. Cookies & Tracking Technologies

    OnlinePDFPro uses the following third-party services that may set cookies in your browser:

    • Google Analytics: We use Google Analytics to collect anonymized, aggregate data about website traffic (e.g., page views, popular tools, geographic region). This helps us improve our tools. Google Analytics may set cookies to distinguish unique users and sessions. Your IP address is anonymized before storage.
    • Google AdSense: We display advertisements through Google AdSense to keep our tools free. Google AdSense may use cookies to serve ads based on your prior visits to our website or other websites. You can opt out of personalized ads by visiting Google Ads Settings.

    Important: None of these tracking technologies have access to the files you process using our tools. File processing is strictly local and completely separate from analytics or advertising.

    5. Analytics

    We use Google Analytics to understand how visitors interact with our website. The data collected is anonymized and includes basic information such as browser type, operating system, and pages visited. We do not collect any personal information or data about the files you process.

    6. Third-Party Libraries

    Our tools use open-source JavaScript libraries loaded from CDNs (Content Delivery Networks). These libraries may log access requests as part of their normal operation. We recommend reviewing the privacy policies of:

    • unpkg.com (CDN for npm packages)
    • Google Fonts (font delivery)

    7. Hosting

    This website is hosted on GitHub Pages. GitHub may collect basic server logs as part of their service. Please refer to GitHub's Privacy Statement for more information.

    8. Children's Privacy

    Our service is available to users of all ages. We do not knowingly collect any personal information from anyone.

    9. Changes to This Policy

    We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.

    Detailed Privacy Disclosures

    At OnlinePDFPro, we consider user privacy to be a fundamental human right, not merely a feature or an afterthought. This extended section provides explicit, transparent details regarding our data handling methodologies, tracking technologies, and compliance with global privacy regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

    Client-Side Processing Exclusivity

    The cornerstone of our privacy commitment is our exclusive reliance on client-side processing architecture. When you utilize tools such as the PDF Merger, PDF Compressor, or PDF Splitter, the application logic translates into highly optimized WebAssembly (WASM) and JavaScript code that is downloaded to your web browser.

    Consequently, the actual manipulation of your files—whether it involves parsing PDF metadata, reordering pages, or compressing image streams—occurs entirely within the isolated sandbox environment of your local operating system. Your files are never transmitted across the internet to our servers. Because we never receive your files, we fundamentally cannot view, store, index, share, or lose your data.

    Data Controller vs. Data Processor

    Under the definitions established by most privacy frameworks (including the GDPR), OnlinePDFPro acts neither as a Data Controller nor a Data Processor regarding the contents of the files you manipulate using our tools. Because the files reside exclusively on your local machine and are modified by software executing on your local machine, you retain complete sovereignty over your data.

    Analytics, Telemetry, and Third-Party Services

    While we do not track or store the contents of your documents, we do utilize industry-standard analytics tools (such as Google Analytics) to monitor aggregate, anonymized website traffic. This helps us understand which tools are most popular, identify geographic trends in our user base, and ensure our server infrastructure scales appropriately to deliver our static website assets quickly.

    These analytics services may set cookies in your browser to distinguish unique users and sessions. Information collected typically includes your IP address (which is anonymized before storage), browser type, operating system, referring URLs, and the specific pages you visit on the OnlinePDFPro domain. None of this telemetry data contains personally identifiable information (PII) or any details regarding the files you process.

    Advertising and Monetization

    To keep OnlinePDFPro free for all users globally, we utilize third-party advertising networks (such as Google AdSense) to display relevant advertisements on our site. These third-party vendors, including Google, use cookies to serve ads based on your prior visits to our website or other websites across the internet.

    You may opt out of personalized advertising by visiting Google's Ads Settings or by using tools provided by the Network Advertising Initiative (NAI). Please note that even if you opt out of personalized ads, you will still see advertisements; they will simply be contextually based on the content of the current page rather than your browsing history.
