How to put a watermark on a photo in bulk?

Question

Watermark

All the best and Happy New Year to you!
Dear experts, tell me a program for applying a watermark to images, but since there are a lot of images, it is necessary that the program processes them in bulk and preferably with the preservation of all folders and subfolders and, what is important, that it does not compress images i.e. left the original quality.

Answer 2

I would open Photoshop, write down the script: Open -> put the image -> send to the lower left corner -> Save as
Then I would click File -> batch processing, and so I would choose the created script, and processed at least 10,000 images.
