AppRanks verdict
Generated from live marketplace data — refreshed daily
PDF Gallery Viewer is a category-leading WordPress app with a limited review volume. Category data on the canonical marketplace listing is currently incomplete, so AppRanks falls back to platform-wide rather than category-relative comparison for this listing. 2 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

- +High average rating (5.0★) signals consistent merchant satisfaction

How PDF Gallery Viewer works
Show full descriptionShow less
PDF Gallery Viewer allows you to easily embed PDF galleries with live previews. 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]
