SplitPDF

A PDF often encompasses many pages of content. This is often convenient as the PDF can keep together lots of info in one easily accessible file.

On the other hand, this can sometimes be too much of a good thing. For example, if the PDF is a book, then it may be easier to navigate by having a separate PDF of each chapter. Or if emailing as an attachment, the size of the file can be pared down to the one or two pages of interest.

In other words, there are plenty of times that it is appropriate to split a PDF and "unmerge" it. One convenient method is to use an online site such as SplitPDF. No account is needed, and you simply upload the PDF, indicate the pages to extract, and in a jiffy the new PDF can be downloaded. Also, the original is left untouched, as only the uploaded copy goes under the knife.
