PDFs (Portable Document Formats) are commonly used for sharing documents. However, sometimes we may need to merge multiple PDF files and create a single document. This is where combining PDFs comes in handy. Whether you need to merge several invoices into one file or merge multiple chapters of a book for a project, it’s a useful skill to have. In this article, we will cover different methods of combining PDFs.

Step-by-Step Tutorial

Combining PDF files can seem daunting, but it’s a straightforward process. Here are the steps:

1. Open the first PDF file
2. Click on ‘View’ in the toolbar and select ‘Thumbnails’
3. A sidebar with thumbnails of each page will appear.
4. Drag the second PDF file to the sidebar.
5. The pages of the second PDF file will appear in the thumbnail sidebar, after which you can drop them into the desired order.
6. Save the merged PDF file.

It’s that simple. If you’re working with a large number of PDF files, it’s best to combine them in small batches instead of merging everything at once. This will make the process smoother.
