The above tool, created by Maximka, “is based on original script with many feature additions”. It’s the same, but with user interface (for Windows).

Do these tools download the best-resolution images?

Yes. See the ad.txt file:

“# Image resolution (10 to 0, 0 is the highest), [default 0]”. Just leave “0” there.

@Wankata @chehongzhi @bud I am deeply appreciative of the insight you provided. Your gracious assistance has left me feeling privileged and indulged.

Thank you all!

Unfortunately no…


For me, downloading in JPG format is an advantage - I download dictionaries exclusively, and it is important to be able to search in them, e.g. they must be recognized. So before recognition, I can process the photos with a program like FastStone Photo Resizer (unify the size of the photos, make preliminary corrections, especially if the pages will be in color, etc.). Otherwise, with Adobe Acrobat, I combine and print the photos through a virtual printer to an acceptable size, for example A4 or B5 (by default they are usually very large).

Thank you all the same, dear brother. You see, you have once again broadened my knowledge with the FastStone application. :watermelon: :watermelon: :watermelon:
