    Frequently Asked Questions

    Runs on your device, not our servers

    This page uses browser APIs (Canvas, WebAssembly, workers, etc.) so your files stay on your machine.

    • Processing happens in this tab — close the tab and the session ends.
    • No ZapFile account is required and we do not store your uploads (there are none).
    • Download only what you choose; nothing is sent to us for “cloud processing.”
    • Verify it yourself: DevTools → Network while using a tool — you should not see your file bytes uploaded to ZapFile.
    • Add ZapFile to your home screen for a faster app shell and offline access to cached pages (tools still need a capable browser).
