ACS PDF Slide Viewer

ACS PDF Slide Viewer adds a lightweight block for embedding PDF slide decks in posts and pages.

Upload or choose a PDF in the block editor, set the number of pages, and display it as a fitted slide viewer. Visitors can move forward and backward, zoom in or out, optionally use carousel playback, and download the PDF if you enable the download link.

The front end uses vanilla JavaScript with bundled PDF.js rendering. It does not use jQuery, external CDNs, remote APIs, tracking, or third-party services.

PDF.js 6.0.227 is bundled under the Apache License 2.0. The bundled files are loaded from this plugin directory on the same WordPress site. The original human-readable source is available from the Mozilla PDF.js project:
