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: https://github.com/mozilla/pdf.js https://www.npmjs.com/package/pdfjs-dist/v/6.0.227 #### Features * PDF upload/selection from the block editor. * Automatic PDF aspect ratio fitting with manual presets for widescreen, standard, and A4 PDFs. * Previous and next slide controls. * Zoom in, zoom out, and fit controls. * Optional carousel playback. * Optional PDF download link. * Lightweight vanilla JavaScript front end. * Classic Editor shortcode support. #### Shortcode You can also embed a PDF with: ``` [acs_pdf_slide_viewer url="https://example.com/slides.pdf" pages="8" title="My slides" aspect_ratio="16 / 9" download="true"] ``` ## Screenshots [⌊Inline PDF slide viewer on the front end with navigation, zoom, fit, page status, and an optional download link.⌉⌊Inline PDF slide viewer on the front end with navigation, zoom, fit, page status, and an optional download link.⌉[ Inline PDF slide viewer on the front end with navigation, zoom, fit, page status, and an optional download link. ## Blocks This plugin provides 1 block. * ACS PDF Slide Viewer Embed a PDF as a slide viewer with previous/next controls, carousel playback, and download options. ## Installation 1.

No. PDF.js is bundled with the plugin and loaded from your own WordPress site. ### Why do I need to enter the page count? PDF.js reads the document for rendering, but the block stores a page count so the editor settings, server-rendered markup, previous/next controls, and carousel state have a predictable fallback before the PDF has finished loading in the browser. ### Does this plugin send PDF files or visitor data to another service? No. PDF files are rendered in the visitor’s browser using bundled PDF.js files served from your WordPress site. The plugin does not send PDFs, visitor data, or usage data to ACS or any third-party service. ### Can visitors download the PDF? Yes, but only if you enable the download option in the block settings. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ACS PDF Slide Viewer” is open source software.
