Every day, millions of people upload their most sensitive documents—contracts, tax returns, medical records—to online PDF tools. What most don't realize is that these tools are reading and storing every single file.

The Hidden Cost of "Free" PDF Tools

When you use a typical online PDF merger or compressor, here's what actually happens:

1Your file is uploaded to their server
2It's processed on their infrastructure
3A copy may be stored for "processing" or "improvement"
4Your data passes through multiple systems

Even if they claim to delete files after processing, you have no way to verify this. Your confidential merger agreement or personal tax return could be sitting on a server somewhere, vulnerable to breaches.

Real Privacy Risks

Data breaches

Major PDF services have been hacked, exposing millions of documents

Employee access

Staff at these companies can potentially view your files

Third-party sharing

Many services share data with analytics and advertising partners

Government requests

Your documents can be subpoenaed from their servers

The Alternative: Client-Side Processing

TrustFile takes a radically different approach. Instead of uploading your files, we process everything directly in your browser using WebAssembly technology.

What this means for you:

✓ Your files never leave your device
✓ No server ever sees your documents
✓ Works completely offline
✓ Mathematically impossible for us to access your data

How to Verify

Don't just take our word for it. Open your browser's Developer Tools (F12), go to the Network tab, and use any TrustFile tool. You'll see zero file uploads. That's not a promise—it's architecture.
