Tutorial - How to Merge PDF Files?
Introduction
Why would you want to merge PDF files? Maybe you're a student who has a bunch of papers you've collected for research; or maybe you're adding a cover to an eBook you've written. Or perhaps you want to rejoin the pages of a PDF that you split with PDF Chain. Advanced PDF Utilities Free provides a PDF merger to join PDF files into one easy-to-read file.
Step 1. Input PDF Files
Launch Advanced PDF Utilities Free and click "PDF
Merge" tab. Click "Add" to input PDF
files that you want to merge into a new PDF file. Press Ctrl
or Shift key to select multiple PDF files in the Open dialog.
Click "Open" to input them to the PDF merger
window.

Step 2. Arrange File Order
Detailed information such as file name, location path, file size, etc. of each added file is displayed. Use "Remove" or "Clear" to delete the unwanted task. To arrange the file order, click "Move Up/Move Down" buttons or just select the file and drag it the place according to your schedule.
Step 3. Start Merging
When you have added all the files to be merged and have the files in the desired sequence, Click "Merge PDF" to select an output folder for the new PDF file. Click "OK" and the merging process will be finished in seconds.
