 * Is it possible to automatically add the watermark to images without changing 
   their file size.
 * In settings -> Jpeg quality -> default (-1) makes the file sizes smaller and 
   lossy. What is the best number – 1 to 100 – to keep them the same size as when
   they were uploaded?

 * Hello,
 * Unfortunately, the only option is to experiment with different settings and see
   what comes out, as it depends on the level of compression of the image before
   uploading, and it is not possible to read that out of the compressed image.
 * 0 is the maximum compression, 100 is no compression (or minimal) therefore the
   largest file size. The default value (-1) is equal to the settings around 75.
