Why You Should Never Upload PDFs to Online Tools

Sensitive documents — contracts, IDs, invoices — deserve true privacy. Most online PDF tools upload your files to external servers, which can introduce risk.

The Risks of Uploading PDFs

• Third-party storage or logging of your files
• Metadata leaks
• Potential model training on uploaded content
