Using desktop software like Adobe Acrobat/Acrobat Pro (NOTE: Adobe Acrobat is the paid-for version, not the free Adobe Reader). You can download and use Adobe Acrobat on a trial basis (click the link above, then click the Free 30-Day trial button on the right).
A popular option is SmallPDF available for both PC and MacOS as well as being a Chrome Plugin. This software is like Adobe, it is based completely on editing PDFs. You can do this fully online or by installing the tool. The only downside is that you can use it for free only twice per hour.
