WordPress PDF Viewer is the easiest way to embed PDF files on your WordPress site and let visitors read, search, and zoom through documents directly in the browser — no download required. Powered by Mozilla’s PDF.js engine, it works in every modern browser and on mobile devices, and integrates tightly with WordPress Download Manager Pro so even password-protected and members-only PDFs can be previewed safely.
Unlike Google Doc Viewer (the default fallback in WPDM Pro), this add-on renders PDFs locally in the visitor’s browser, so private files never leave your server. When a package has multiple PDFs attached, you can show all of them in a switchable preview gallery using the [pdf_gallery] template tag.
Key Features
- Inline PDF preview — embed any PDF on a page or post using the
[doc_preview]template tag - Multi-PDF gallery — show multiple PDFs in a switchable preview gallery using
[pdf_gallery] - Office document support — preview
.doc,.docx,.ppt,.pptx,.xls,.xlsxfiles via the Microsoft Office Online viewer - Password-protected PDF viewer — visitors unlock the document with a password before viewing
- Print & copy protection — disable right-click and printing for sensitive documents
- Dark mode — auto-syncs with your WPDM color scheme (Light, Dark, or System)
- Full PDF.js toolbar — search, zoom, rotate, thumbnails, outline, page navigation, presentation mode
- Mobile-friendly — responsive layout that works on phones and tablets
- Quick preview button — every PDF and Office file in your package file list gets a preview button that opens the document in a Fancybox modal
