Instructions:

Get an image from your PC and drag it over the left frame. Or get an test image from the top of the page and drag it on that frame.

You will get the original file binary on the left and the new generated (from this library) binary on the right side.
On the right frame, you will see a human formatted list of attributes of this JPG. Just move the mouse over every attribute to see where the attibute is located in the file.

This tool is good if you are creating a JPEG by yourself and want to check if it is wrote like expected.

Note: This is just a test. Many tags are still missing! Just use it as it is. Press F12, to open the console, if you want to see more info about your JPG!

Tipp: Press the right button on an image to parse the exif section and get a list directly on this page!
