How to install Poppler on Windows?

Other answers have linked to the correct download page for Windows users but do not specify how to install them for the uninitiated.

1. Go to this page and download the binary of your choice. In this example we will download and use poppler-0.68.0_x86.

2. Extract the archive file poppler-0.68.0_x86.7z into C:\Program Files. Thus, the directory structure should look something like this:

C:
    └ Program Files
        └ poppler-0.68.0_x86
            └ bin
            └ include
            └ lib
            └ share

3. Add C:\Program Files\poppler-0.68.0_x86\bin to your system PATH by doing the following: Click on the Windows start button, search for Edit the system environment variables, click on Environment Variables..., under System variables, look for and double-click on PATH, click on New, then add C:\Users\Program Files\poppler-0.68.0_x86\bin, click OK.

4. If you are using a terminal to execute poppler (e.g. running pdf2image in command line), you may need to reopen your terminal for poppler to work.

5. Done!
