6. Merging several documents into one .pdf file

If you have a number of .pdf files you wish to merge into one document, there are a lot of programs you can use, but in our opinion, possibly the simplest way to do it is by going to the website MergePDF which does not require any installation. After you go to this website, click on the option BROWSE and select all the files you wish to merge, then click on OPEN and wait until every file is uploaded. When the uploading is completed, click on MERGE PDF FILES to start the merging process.

Finally, click on DOWNLOAD to download the merged document.
