How to add a PDF to a WordPress Page or Post
Do you have PDFs or Word documents that you’d like to share on your WordPress website? It’s pretty easy to insert or link to a PDF in WordPress, but the steps to do so may not be obvious. Linking to a PDF (or Word Document) is similar to adding an image in WordPress, but there may some additional steps, depending on what you would like to do.
1. Place your cursor where you want the document link to go and click on the first icon after “Add Media” or “Upload /Insert”:
2. A window will pop up – click on “Select Files”:
3. Go to the folder and click on the doc or PDF you want to upload, then click “Open”:

4. WordPress will upload your file and you’ll see something like this:
5. Change the wording in the Title to be what you want to show on your website as the link. So for example, “Click here to download the PDF” or in this case, “Emergency Manager Phone Numbers.”
6. Now copy the Link URL here, making sure you copy the entire path all the way to the “.pdf” You will see why copying that now is helpful later. If there’s no Link URL shown, just click the “File URL” button.
7. Then click “Insert into Post”. You should end up with something that looks like this.
8. Click Update and View your live page or post. Always click on your link to test that the PDF works!
