You can glue pdf documents in different ways, for example, using a product from Adobe - Acrobat Professional. However, there are free options, for example, a utility from Google - PDFBinder.
Necessary
PDFBinder program
Instructions
Step 1
Download the program (the download link is at the very end of the article) and, by double-clicking on the setup file icon, start the installation. The utility has an English-language interface, but this should not put you off, because the steps required, both in installation and in use, are obvious and intuitive. This guide should be enough for you.
Step 2
In the first window that appears, immediately click Next. In the next one, you can specify a different path for installing the program by writing it manually in the Folder input field, or click on the Browse button by calling the Browse for folder menu and specifying this path in a few mouse clicks. If you click on the Disk cost button, a new window will appear in which the free disk space will be indicated. The setting below allows you to determine which users will be able to use this program. Select Everyone if everyone, or Just me if only you. After understanding the settings, click Next. In a new window, the installer will notify you that the program is ready for installation. Click Next again. The installation will begin. When finished, click Close.
Step 3
Look for the program icon in the directory that you specified during installation. By default, it should be C: / Program Files / PDFBinder. The icon looks like a notebook sheet, on which three arrows are directed from the left: blue, red and green.
Step 4
Double click on the icon. The program window will appear. Click Add file, in a new window select the required pdf-file and click "Open". A line will appear in the central window of the program, in which the path of the added file will be indicated. Add other files in the same way. The order of the files in the central window of the program determines their final location in the final file. Use the arrows to move the files in this list. To remove a file from the list, left-click on it and click on the button with the "Stop" sign.
Step 5
Once you're done with the settings, click Bind! In the new window, specify the path for the final file, its name and click "Save". Ready.
