Tracking pixel detector

See what would phone home before it loads.

The local scanner lists remote image hosts and highlights tiny, hidden, or tracker-like resources while every external image remains blocked.

Questions about this workflow

Does detection load the tracking pixel?

No. It reads the image URL and HTML attributes from the saved file without requesting the resource.

Are all remote images trackers?

No. Some are ordinary logos or content images, which is why the report distinguishes remote images from stronger tracking indicators.
