The Portable Document Format (PDF) is one of the most commonly used file types around.
PDFs are primarily shareable text or photo documents accessible to anyone who has a computer or smartphone. Unlike a Word file, which requires Microsoft Word to view or edit, most browsers will open a PDF.
That’s useful when sharing files with friends or colleagues, especially if you don’t know what software they have; PDFs are the one-size-fits-all option. You can also be sure your document’s format won’t change regardless of what kind of device is accessing your file.
But let’s say you have one or more documents to share. Instead of sending multiple attachments in an email, you can combine and organize multiple PDFs into one file.
Mac users can do this using the Preview app that comes with your computer.
PC users will have to download software, but many of these programs are free and easy to use.
