Can you tell me a web service for determining the coordinates of a point on an image when hovering over with the mouse?

Question

JavaScript

Tell me a web service where, after loading an image, you can hover over any part of it with the mouse and see the coordinates of this point relative to the image (x and y). It is clear that you need a very simple thing and you can write it yourself in PHP + JS, but surely you already have it ready? We need a web solution so that users of any OS can use it.

Answer 1

Another option is to use the editor. For example Pixlr . But this is from a cannon to sparrows.

Answer 2

Something like this?
jsbin.com/uvesoq/1/edit

Answer 3

Open the image in Paint
Move the cursor over the pixel you are interested in. The pixel
coordinates are displayed at the bottom left of the panel.
