How to Verify That a Web Tool Never Uploads Your Files

Why Local Processing Matters

When you convert a sensitive document, crop a photo with personal data, or merge tax PDFs, you shouldn’t have to trust a remote server.

At Nimbzo, our tools execute entirely inside your browser session using native Web APIs like HTML5 Canvas and WebAssembly.

How to Verify In Any Modern Browser

You do not need to take our word for it. You can independently confirm that zero bytes are uploaded:

1. Open Developer Tools: Press F12 or right-click anywhere and select Inspect.
2. Switch to the Network Tab: Clear existing requests by clicking the round “Clear” icon.
3. Drop Your File: Process an image or document in the tool.
4. Inspect the Activity: Look at the request log. Notice there are no POST, PUT, or multipart payloads sending file data across the internet.

Your device does all the computation, preserving your privacy entirely.
