It uses PDF.js to render the first page of each PDF directly in the browser, without relying on server-side libraries like Imagick. Each item includes a customizable title and a “View” button that opens the PDF in a modal viewer. The layout is responsive and adapts from a multi-column grid to a single-column stack on smaller screens. **Key Features:** * Live thumbnail of first PDF page (via PDF.js) — lazy-loaded via IntersectionObserver * Responsive layouts (Grid, List, or Slider) * Modal viewer with zoom, navigation, and download * Gutenberg block with layout selector and drag-and-drop file integration * Tooltip + truncation for long titles * Dynamic shortcode generation by category, tag, or post * Sorting UI (Title / Filename / Manual drag & drop) * Manual ordering with FIFO/LIFO behavior for newly added items * Zero external requests — all assets (PDF.js, Font Awesome, Swiper.js) served locally * Assets only load on pages that contain a gallery * Settings page (Settings > PDF Gallery Viewer) for site-wide accent color, surface color, text color, corner radius, and default layout * Per-gallery accent color override via the `accent_color` shortcode/block attribute ### Usage Basic usage: [pdf_gallery url=”https://example.com/doc.pdf” title=”Document Title”] Multiple items in a container: [pdf_gallery_container layout=”grid”] [pdf_gallery url=”…” title=”…”] [pdf_gallery url=”…” title=”…”] [/pdf_gallery_container] Sorting / ordering: [pdf_gallery_container layout=”grid” order_by=”title” order=”asc” ui=”1″] … [/pdf_gallery_container] Manual ordering (UI drag & drop) with FIFO/LIFO for newly added items: [pdf_gallery_container id=”my-gallery” layout=”grid” order_by=”manual” manual_mode =”fifo” ui=”1″] … [/pdf_gallery_container] IMPORTANT: Manual ordering is managed by admins and saved server-side (post meta) so the order is the same for all visitors. For reliable persistence, always set a stable id=”…” on each container (the Gutenberg block does this automatically). Dynamic by category: [pdf_gallery_container category=”brochures” layout=”slider”] Per-gallery accent color (overrides the site-wide default set in Settings > PDF Gallery Viewer): [pdf_gallery_container layout=”grid” accent_color=”#ff6600″] … [/pdf_gallery_container] ## Screenshots [⌊Admin PDF list — manage, edit, and delete gallery items⌉⌊Admin PDF list — manage, edit, and delete gallery items⌉[ Admin PDF list — manage, edit, and delete gallery items [⌊Responsive gallery grid layout⌉⌊Responsive gallery grid layout⌉[ Responsive gallery grid layout [⌊Gutenberg block editor — inserting a PDF Gallery block⌉⌊Gutenberg block editor— inserting a PDF Gallery block⌉[ Gutenberg block editor — inserting a PDF Gallery block [⌊Modal viewer with zoom, navigation, and download controls⌉⌊Modal viewer with zoom, navigation, and download controls⌉[ Modal viewer with zoom, navigation, and download controls [⌊Slider layout (Swiper.js)⌉⌊Slider layout (Swiper.js)⌉[ Slider layout (Swiper.js) [⌊Tooltip and truncation for long titles⌉⌊Tooltip and truncation for long titles⌉[ Tooltip and truncation for long titles ## Blocks This plugin provides 1 block. * PDF Gallery (Multiplo) Inserisci una galleria PDF con più documenti. ## Installation 1.

It’s great to not have to manually create thumbnails for a PDF gallery. They’re generated on the fly and look good. It works OK with the block editor so you don’t have to use shortcodes, though the block editor interface is not WYSIWYG, it gets the job done. I’d like some more customizing options but maybe they will come in the future. ![](https://secure.gravatar.com/avatar/989ff1e7ea92563579ac5da2ecfd1c56f82003b6c1ab0eb547a04701da84fa2e? s=60&d=retro&r=g) ### 󠀁[Clean, lightweight, and works beautifully!](https://wordpress.org/support/topic/clean-lightweight-and-works-beautifully/)󠁿 [manygold](https://profiles.wordpress.org/manygold/) މެއި 2, 2025 I’ve tried several PDF gallery plugins, but PDF Gallery Viewer stands out for its simplicity and modern design. The real-time thumbnail previews using PDF.js are fast and accurate, and the Gutenberg block integration is seamless. I especially love the layout options—grid, list, and slider—which make it super flexible for different use cases. No server-side dependencies, fully responsive, and easy to use.Highly recommended for anyone who wants a professional and efficient PDF gallery on their WordPress site!
