How can I verify my files aren't uploaded?

Open your browser's developer tools (F12) and watch the Network tab while merging. You won't see any file upload requests - all processing happens locally.

Is this merger safe for confidential business documents?

Yes, since no data leaves your device, it's safe for confidential contracts, HR documents, financial records, and any sensitive business materials.

Does local processing affect merge quality?

Not at all. The same PDF libraries used by server-based tools run in your browser. The only difference is where the processing happens.

Can my IT department approve this tool?

Yes, IT teams often prefer browser-based tools that don't upload data. The local processing model eliminates data transfer security concerns.
