Privacy Policy
Last updated: August 19, 2026
Your privacy is not just a policy for us — it's the foundation of how we built this product.
1. Your Files Stay Yours
PDF Compressor Ai processes everything in your browser using client-side technology. Your PDFs are never uploaded to any server, never stored on any disk, and never leave your device. When you close the tab, your files are gone.
2. What We Collect
Because all processing happens locally, we don't collect or store any of your documents. We may collect anonymous, aggregated analytics (such as page views) to understand how visitors use the site and improve our services. This data cannot be traced back to you or your files.
3. Local Storage
We use your browser's local storage to remember your theme preference (light or dark mode) and your compression settings. This data stays on your device and is never transmitted anywhere. You can clear it at any time through your browser settings.
4. Third-Party Services
Our site loads the PDF processing libraries from public CDNs (Content Delivery Networks) to provide the fastest experience. These libraries are loaded directly from the CDN and do not receive your files. We may also use standard analytics tools to measure site traffic.
5. Cookies
We use minimal cookies for essential functionality, such as remembering your preferences. We do not use cookies for cross-site tracking, advertising, or profiling.
6. Contact
If you have any questions about this Privacy Policy, please contact us through the contact information provided on this site.
