Step3
Click the 'Combine Files' icon on the top left portion of the screen.
Step4
The 'Combine Files' window that pops up is divided into three sections. The first section is titled, 'Choose the files you wish to combine'. Select the 'Add Open Files' option.
Step5
Select the other open .pdf documents on your desktop when prompted.
Step6
Rearrange the documents as you wish in the second window, titled, 'Arrange the files in the order you want them to appear in the new PDF'
Step7
The final window, titled, 'Choose a file size and conversion setting' allows you to control the size of your merged PDF document. Consider the purpose of your new document. If its to be sent as an e-mail attachment, use a low size setting. If the PDF contains images or is to be used for presentation, choose a high setting. When finished, select 'Next'.
Step8
A final choice: choose between either a single PDF document, or a PDF package, which comes with the option of creating a specialized cover sheet. When finished, hit 'Create', and save to your preferred location.
Tips & Warnings
Double check the PDF documents prior to merging to make sure all pertinent information is included. Its much easier to re-create a single PDF page than a multi-page document.
