I extracted one page of a document with 106 pages and 13210KB of size. The new document, composed by the sole page I extracted, has a size of 13615KB. How is that possible?
I also tried to do the reverse operation, i.e., removed all pages of the document except the one I wanted to keep and the result is the same.
That occured in both offline app and online.

I suspect that the PDF was built so that each page references and includes all of the data in the PDF, and thus the PDF does not get smaller. But I can only say more exactly when I have seen the PDF. It may help to reduce the size of the PDF beforehand to resolve the references.

Dear Stefan,
Thank you very much for your help. I can't send you the document through here, but you can find similar documents in this link:
https://inpi.justica.gov.pt/en-gb/Industrial-Property-Bulletin
You can click in any of the links saying "Boletim da PI (date)". These are industrial property bulletins from the Portuguese patent office.
If your suspicions are correct, how can I overcome that? I know that I can just "print" the page I want into a pdf. But if I do it with pdf24 printer, gives an error. With microsoft print to pdf, for example, it looses quality and looses the hyperlinks the page may contain (which, in this case, are important).
thx!
