Adobe Acrobat is a powerful tool for creating, editing, and viewing PDFs, but the full version of the software is also incredibly expensive. Aside from using built-in Windows 10 programs, there is an online alternative called TinyWow that makes things much easier and faster. The format is completely platform-agnostic, capable of being used, read, and edited by Windows, Mac OS, iOS, Android, and nearly any other platform under the sun. PDFs are one of the most useful file extensions for any device.
