Network Inspector
Monitor all network requests while using our tools. Verify for yourself that your files never leave your device.
Live Network Monitor
Start monitoring, then use any tool. The monitor will track all network activity.
How to Verify Manually
Open DevTools
Press F12 (or Cmd+Option+I on Mac) to open your browser's Developer Tools.
Go to Network Tab
Click the 'Network' tab in DevTools. Click the clear button to start fresh.
Process a File
Use any of our tools (compress PDF, remove background, etc.) while watching the Network tab.
Verify Zero Requests
You should see zero external requests. Only internal framework assets (/_next/) will appear.
Technical Details
This monitor uses the browser's PerformanceObserver API to capture all resource timing entries. It categorizes each request as internal (same-origin framework assets) or external (any cross-origin request).
During file processing, you should see zero external requests. All processing uses WebAssembly, Web Workers, and Canvas APIs that run entirely in your browser without network access.
