How It Works
- Upload a PDF to your media library

FAQ
-
Why aren’t previews being generated?
-
Preview generation requires ImageMagick or Ghostscript on your server. Go to Settings PDF Viewer Server Info to check your server capabilities. Many shared hosts have ImageMagick pre-installed.
-
Can I regenerate previews for existing PDFs?
-
Yes! Go to Settings PDF Viewer Tools and click « Process Unprocessed PDFs » to generate previews for all PDFs in your media library.
-
How do I change the preview quality?
-
Go to Settings PDF Viewer and change the « Preview Quality » setting. Higher quality means sharper previews but larger file sizes.
-
Does this work with page builders?
-
Yes! Use the shortcode [pdf_viewer id= »123″] in any page builder that supports shortcodes. The Gutenberg block works natively in the WordPress editor.
-
Is it accessible?
-
Yes! The viewer includes full keyboard navigation, ARIA labels, screen reader announcements, and respects reduced motion preferences.
-
Can visitors download or print the PDF?
-
Yes, the toolbar includes download, print, and fullscreen buttons. You can disable these in the block settings or plugin options.
