PDF Security and Privacy
How PDF Tool Site keeps PDF work private by processing files in the browser and reducing server-side exposure.
No processing uploads
PDF tools are designed to work without sending documents to a backend processor.
Local file handling
Files stay under browser and device controls while tools run locally.
Private by design
The product is structured so the site operator does not need to inspect your documents.
Client-side PDF processing
PDF Tool Site is built around browser-side processing. When you choose a tool, the app loads the needed JavaScript or WebAssembly code and performs the PDF operation on your device where the browser allows it.
No intentional file uploads
There are no application API routes for uploading PDFs to a processing server. This helps keep sensitive files on your device instead of moving them through a hosted backend.
Your browser may still request application files, scripts, fonts, and static assets needed to display and run the website.
What remains your responsibility
- Use an up-to-date browser and operating system.
- Avoid handling sensitive documents on shared or untrusted devices.
- Clear browser site data after working with confidential files on a shared computer.
- Review final PDFs before sharing, filing, signing, or archiving them.
