Once you have logged onto WordPress, go to your media library. Choose the PDF from your computer that you would like to upload, and drag it onto the webpage screen. Once the page turns blue and says “drop files to upload,” you can drop your PDF.
Once your PDF has uploaded to the Media Library, double click on the image. It will pull up a page that it titled “Attachment Details.” Look down the right side of this screen until you see “Copy Link.” Triple click to select it all, then do Control/Command + C to copy the URL.
Once the URL for your PDF document is copied, go to to the page or post that you want to add the link to. Select the text that you want to link back to the PDF, then choose the “Add Link” button in the text bar.
This will bring up a paste box directly above the text that you have highlighted. Command/Control + V to paste the URL into the box. Once it is pasted, you need to click the arrow button next to your URL to save it to the text.
Once the link is applied and on the text that you want it to be, you can choose the setting button next to apply. Here you can change if you want your PDF to open into a new tab or not.
