14 Best WordPress PDF Viewer Plugins

The last time you received a document via email, an online portal, or even through a text message, it was probably in PDF format. If you want to do the same on your own WordPress site, you’ll need a WordPress PDF viewer plugin.

Standard WordPress media uploaders can help you upload PDF files, but you may need more comprehensive features to make sure the document shows up exactly as you want it to. So before you upload another PDF to your website, take a look at this list of plugins that offer robust options for controlling the display, functionality, and design of this file format.

But before we dive into the list, let’s discuss what a PDF is and how viewer plugins can be used to your benefit.

What is a PDF?

A PDF (an abbreviation for Portable Document Format) is a standard file format that helps users view documents in a professional and clean interface. This file format lets people view the document as its creator intended, no matter the platform the creator used to produce it.

PDF embeds are easy to save and print, and if you’re running your own website, you can embed them in WordPress. Though, if you want the PDF to be visible on the front end of your site, you’ll first need to upload it on the back end of your site using a PDF viewer plugin.

Benefits of Using a PDF Viewer Plugin

Installing a PDF viewer plugin can help you:

• Keep Website Visitors On Page: Without a PDF viewer plugin, WordPress will show PDF files as links that open in new tabs. You want to increase your visitor’s time on page and have them engage with your content for as long as possible.
• Document Protection: You may want to share documents that shouldn’t be modified by the people that download them. With a PDF viewer plugin, it’ll make it harder for your documents to be edited, and even exclude them from search engine crawling.
• Better Website UI/UX: Large documents can clutter a webpage if they take up too much space. With a PDF viewer plugin, you can keep your document formatted the way you want, without having to sacrifice the appearance of your site or your user’s experience.

Your documents have the potential to help your WordPress website in more ways than one. To help you make the most out of your PDFs, we made a list of our favorite plugins.
