PDF Library Zipper Lite is a lightweight, no‑fluff WordPress plugin that makes it dead‑simple to build a clean, responsive PDF library on any page or post. Visitors see thumbnail previews of your PDFs, select one or more documents, and download them as a custom‑generated ZIP—all without leaving the page.
Key Highlights:
- Front‑end grid: Mobile‑first CSS Grid layout, with adjustable columns and thumbnail sizing.
- Auto‑thumbnails: Generates a crisp PNG preview of page 1 for every PDF using Ghostscript + Imagick.
- Select & ZIP: Optional “Select All” toggle, per‐file checkboxes, and a one‑click Download button that bundles chosen PDFs into a custom name and time‑stamped ZIP.
- Admin settings: Pick grid columns (2–6), thumbnail width, ZIP expiry time, button label, filename prefix—and even enable a manual light/dark‑mode override.
- Zero bloat: No bulky frameworks, no external dependencies beyond WordPress core, Imagick, and Ghostscript.
- Lightweight: 4 files and only 901 LOC
Whether you need a simple resource center, a whitepaper hub, or a user‑friendly download portal, PDF Library Zipper Lite delivers powerful functionality in a lean, easy‑to‑use package—so you can share your PDFs, not your plugin’s code
