PDF tools is a program or app used to work with PDF files, which are documents. Also that look the same on any device. With a PDF tool, you can view, create, edit, and manage PDF files. This includes adding or removing text, images, and pages. Also as well as combining multiple PDFs into one or splitting one into several. Some PDF tools also allow you to convert PDFs to other formats, like Word or Excel, and vice versa. They are handy for handling documents that need to be shared or printed in a consistent format.
