One of the most popular formats for sharing rich text documents across the web is PDF files. They're small in size, can be opened on any device, and are easy to create. Today, we're going to learn how we can merge multiple PDF files into a single PDF file. All we want is to append every file after one another to create a master PDF file. This way, we can easily send a single file instead of remembering to attach or upload multiple files. One does not need to be technically sound to perform the merging operation. It's dead simple and everyone can do it quite easily. Let's learn how to easily merge multiple PDF files.

The tools we're going to share below do not alter the formatting or the style of merged PDF files in any way. You get the exact styling and formatting in the resulting PDF file. The zoom level may change.
Do share your favorite one after trying out all of them. Remember, if the group of files to be merged are big, the merging time will accordingly go up. So, be patient while the merging process is going on.
