Hello dear friends.
Tell me please. The question is about the size of pdf files. The first few books, as well as their articles, were downloaded without size optimization, a 9-page file - 2MB, after optimization, such a pdf file weighs 180kb, which will significantly speed up the download. Each article consists of 3 pdf files, can I replace them with identical (in name and content) but optimized in size without any consequences. By consequences, I mean refusal to index or any other negative influence. I do not consider the possibility of re-adding journals since they already have DOI assigned.
Thanks in advance for your answers!
Can you test this on testing environment?
