I started a subscription to split PDF(ebook). Adobe advertised like it's free to split PDFs, that was the only reason I spent my time on it. So after the subscription I uploaded my PDF to choose some pages to split the document. It went all well until then. When I finish up all the process, suddenly it says my file is too big! It's only 329MB. This is not worthy for subscription. So I ended up just wasting my time.
