You don't want to inflict a half-dozen PDF files on the accounting department, for example, when you can deliver one unified document. Or maybe you have four or five sections of a report that you've printed to separate PDFs from Word, Excel, and a photo editor. How do you get them all into a single file? These questions are all the more pressing for people working from home and those trying to go paperless because PDFs easily replace physical documents. People need to know how to organize and manage them. If you use a Mac, you have the only tool you'll need already built into the macOS operating system. That said, you can find more flexible and full-featured solutions if you buy commercial third-party apps. If you use Windows, you need third-party apps-good thing there are a few free, open-source options that do the job. With any operating system, you can always use an online app that combines and edits uploaded PDFs, but I’m leery about using almost all of them. Some of these sites seem to have no viable business plan, and their PDF-editing services give them the ability to harvest the data in your files, including invisible metadata, that can potentially identify you and your system. You may not want to give that metadata to a site you don’t know anything about, and that site could profit from your data in ways you won't like. I make one exception to this rule: Adobe's free PDF-merge service (Opens in a new window). When you need to combine PDF files in Windows, you might wish you had a Mac because the macOS-only Preview app gets the job done quickly and easily. Windows 10 lets you view PDF files in the Edge browser, but it doesn't let you do anything with them.
