When saving in Photoshop, do you always need to prescribe the format after the dot (mac os)?

Question

JPEG

Hello everyone
There is a problem, constantly when saving in Photoshop, you have to prescribe the format after the dot.
That is, there is a layout in psd, you need to save it in jepeg, let's say (in fact, anyway) I choose when saving jepeg, but at the same time, the format remains psd in the file name

When you need to save a lot of files, this quite annoying, maybe someone knows how to solve this moment.
