What is "save IPTC data" when exporting as jpg?

[snowforest]

Hello,
What does "save IPTC data" mean, when exporting as jpg? Do you recommend it? What happens if we do not check it? it is unchecked by default.

Basically description text entered by a human so likely not there if you have to ask what it is.

If you have a JPG image that already has the IPTC meta data,  and you modify that image in gimp and then save as a JPG with the "save IPTC data" box unchecked, does that erase the previously existing data, or just leave it undisturbed?

If you overwrite the same image then the data is lost.
