Photo editor

Goodmorning to you all, we need to edit some pictures. In particular we need to remove a text which is part of the picture. The file is made up of 7 pages and the text (we need to remove) is on each page. The image under the text and the quality of it must remain the same.
Here below, I attach you as example one of the pages we need to edit.
The text that has to be removed is "www.thlmachine.com".
