No data ever leaves your network
No account, no sign-up, no credit card. Just open a tool and start working.
This isn't a privacy policy you have to trust. It's how the app actually works.
When you open a PDF here, it stays right in your browser. It is never sent to any server. No one else can see it — not us, not anyone. Your files exist only on your computer, and they're gone the moment you close the tab.
There is no server processing your files. Your own computer handles everything — editing, merging, compressing, signing — right inside your browser. It's fast because there's no uploading or waiting in line.
Press F12 on your keyboard to open your browser's developer tools. Click the "Network" tab. Now upload and process any PDF. You'll see that nothing is uploaded. No other PDF tool passes this test.
Turn off your Wi-Fi and the app keeps working. That's how you know nothing is being sent anywhere. Everything runs locally on your device. Perfect for confidential documents, whether you're at home, at work, or on a plane.
