详情介绍:
Turn any PDF into a realistic 3D flipbook on your WordPress site. PDF Rack is a PDF flipbook maker, PDF viewer and PDF embedder in one plugin: upload a catalogue, magazine, brochure, menu, e-book or report and your visitors flip through it like a real book — with page curl, page-turn shadows and click-to-flip — right on your page.
Prefer a classic layout? Every PDF can also be shown in a vertical scroll reader or a page-by-page slider, inline or in a full-screen popup. No iframes, no Flash, no browser plugins and no external service: the PDF flipbook runs in the visitor's browser with Mozilla's PDF.js and WebGL, on desktop, tablet and phone.
Unlike the WordPress Media Library that buries PDFs among thousands of images, PDF Rack gives you a dedicated PDF library to upload, categorise and find documents, then embed them with a Gutenberg block, an Elementor widget or a shortcode in seconds.

常见问题:
Does this plugin modify my existing Media Library files?
Not at all. PDF Rack stores its data separately. Your existing Media Library files remain completely untouched.
Can I use this with the Classic Editor?
Absolutely. Every uploaded PDF gets a unique shortcode (e.g., [pdf-rack id="10"]) that you can paste into the Classic Editor or any text widget.
Is the PDF viewer mobile-friendly?
Yes. The viewer is fully responsive and adapts to any screen width — phones, tablets, and desktops.
Will it slow down my site?
No. The PDF viewer scripts load only on pages where you embed a PDF, so the rest of your site stays fast.
Does it support large PDF files?
The plugin will load any PDF your server allows. For very large files (50 MB+), performance depends on your hosting upload_max_filesize setting and your visitor's connection speed.
How do I create a PDF flipbook?
Upload your PDF in PDF Rack → Add New, then embed it with the PDF Rack block, the Elementor "PDF Viewer" widget or the shortcode [pdf-rack id="123" mode="flipbook"]. The flipbook is built from the PDF on the fly — there is nothing to convert.
Can I embed a PDF without a flipbook?
Yes. Use mode="reader" for a vertical scroll PDF viewer or mode="slider" for one page at a time. Add lightbox="true" to open the PDF in a popup from a button.
Does the flipbook work on mobile?
Yes. Drag or tap a page to turn it, and the flipbook resizes to fit phones, tablets and desktops. On small screens you can also switch to the reader or slider per embed.
Do visitors need to install anything?
No. The built-in viewer runs entirely in the browser — no plugins, extensions, or third-party apps required.
