What the check reads

The check looks at hidden notes stored beside the picture. It does not look at the scene in the picture.

Coordinates

A phone can save where it was when the picture was taken. That place is stored as three pairs of numbers for latitude and three for longitude. The page turns those into degrees north or south, and east or west, and shows five digits after the decimal point. It does not ask a map service what street that is.

Place names

Some files also store a city, state, country, or a shorter place label. The page shows that text when it is in the JPEG photo notes, the Adobe notes, or the PNG text notes. A label is not the same thing as the map point, so the page reports them separately.

What stays in the picture

If a house number is painted on a door, or a street sign is in the frame, that address is part of the picture. Removing the hidden location does not cover it, blur it, or crop it. This page does not read those words.

The copy

The download is a new file. The original on your computer is left alone. In the new file the map point is gone, and a stored city or place label is blanked or removed. The pixels are copied through unchanged.
