Description
Selytho Page Flip Creator renders your PDFs as a hardware-accelerated 3D flipbook directly in the browser. No Flash, no external services, no server-side processing — just upload a PDF, drop in a shortcode, and your visitors get a beautiful page-turning experience instantly.
The engine is built on Three.js (WebGL) with PDF.js for client-side rendering. Pages curl realistically with configurable curl amount and flip speed. The viewer is fully responsive and works on desktop, tablet, and mobile.
WebGL Rendering
Smooth, hardware-accelerated page turns powered by Three.js. Cylindrical vertex deformation gives each page a natural curl. Front and back faces are rendered as separate meshes with correct UV mapping and depth ordering.
PDF.js Powered
PDF pages are rendered client-side by PDF.js — no server-side image conversion or pre-processing required. Simply provide a PDF URL. All rendering happens in the visitor’s browser.
Flipbook Editor
Each flipbook has its own settings page in the WordPress admin with a live preview that updates as you change settings. Configure appearance, controls, info panel, and Pro features all in one place.
Info Panel
Display PDF metadata — title, author, subject — in an elegant overlay panel. Override any field per flipbook. Supports custom colours and an optional logo (Pro).
Share Panel
Built-in share overlay with social sharing links — Facebook, X (Twitter), LinkedIn, Pinterest, BlueSky, and email — plus a one-click copy button for the page URL.
Bookshelf Mode
Group multiple PDFs into a single flipbook with a shelf selector. Each book in the shelf has its own info panel overrides.
View Statistics
Track views, pages seen, and read depth per flipbook session. A dedicated Statistics page shows all-time totals and a per-flipbook breakdown with inline bar charts.
RTL Support
Right-to-left page order is fully supported. Enable RTL per flipbook or as a global default. All text inputs in the admin panel support bidirectional text entry.
Viewer Settings Panel
Visitors can adjust flip speed, curl amount, interaction mode, and pan direction in real time from a settings panel in the controls bar — without reloading the page.

Uninstall
Data removal is opt-in. By default, deleting the plugin preserves all your data so it can be re-installed without loss. If you enable Settings Delete data on uninstall, then deleting the plugin removes all plugin data from your WordPress database, including:
- All view records (
slyth_viewstable) - All flipbook post meta (
_slyth_*keys) - All plugin settings and options prefixed with
slyth_ - Licence key and validation data
The uninstall script does not delete:
- Your PDF files — these remain in the Media Library
- Any site content — posts, pages, users, WooCommerce data, etc.
Disclaimer
Selytho Page Flip Creator is provided as-is, without warranty of any kind. Rob Snow / Rob Art | WordPress Development accepts no responsibility or liability for data loss or any damage arising from the use of this plugin. You are solely responsible for ensuring your use of this plugin complies with applicable law in your jurisdiction.
PDF rendering is performed client-side by PDF.js. Rendering quality and performance depend on the visitor’s device and browser. Very large PDFs may load slowly on low-powered devices.
External Services
Selytho Page Flip Creator does not connect to any external services during normal operation. All PDF rendering is performed client-side in the visitor’s browser using PDF.js. No visitor data or content is transmitted externally.
Licence validation communicates with the Rob Art licence server at https://robsnow.eu solely to verify your Pro licence key. This only occurs when you activate or deactivate a licence from the Settings page.

FAQ
-
Is Selytho Page Flip Creator free?
-
Yes. The core plugin is free and includes the WebGL viewer, flipbook editor, bookshelf mode, info panel, share panel, view statistics, and all free controls. Pro features — soft flip style, auto-flip, zoom, pan, fullscreen, thumbnails, sound, and advanced controls — are available with a Pro licence.
-
Does it require any server-side processing?
-
No. PDF pages are rendered entirely in the visitor’s browser by PDF.js. You simply provide a URL to any publicly accessible PDF file.
-
Will it work with any PDF?
-
Yes, as long as the PDF is publicly accessible via a URL. PDFs served with restrictive CORS headers may fail to load — host the file on the same domain as your WordPress site or ensure appropriate CORS headers are set.
-
Does it work on mobile?
-
Yes. The viewer is fully responsive. Touch drag-to-flip is supported on mobile and tablet.
-
Can I embed multiple flipbooks on one page?
-
Yes. Each shortcode initialises its own independent viewer instance.
-
Will it slow my site down?
-
Selytho only loads its scripts and styles on pages where the shortcode is present. Three.js and PDF.js are served from your own server — no external CDN requests are made.
-
What happens to data when I deactivate the plugin?
-
Deactivating the plugin stops tracking but preserves all data. Data is only removed when the plugin is deleted, and only if you have enabled Settings Delete data on uninstall (off by default).

Changelog
1.3.15
- Updated the Pro upgrade link to the live checkout
1.3.14
- Renamed the internal admin menu identifiers and the shortcode to use the plugin’s unique “slyth” prefix, avoiding any possible clash with other plugins
- The shortcode is now [slyth_flipbook] (if you previously used the older tag, update your embeds to [slyth_flipbook])
1.3.13
- Soft page-curl is now provided entirely by the Pro add-on — the free build no longer contains any disabled or restricted soft-curl code (full WordPress.org trialware compliance)
- Control bar position, mode and distance are now available to everyone in the free editor’s Controls panel
- Primary shortcode is now [slyth_flipbook]; the original [selytho] shortcode continues to work, so existing embeds are unaffected
- Hardened input handling on the admin screens (all request reads are now explicitly sanitised)
1.3.12
- Updated the bundled 3D engine and PDF rendering libraries to their current releases (resolves an out-of-date PDF library with a known security advisory)
- The info-panel logo is no longer part of the free build at all — the free viewer shows the Selytho logo, and a custom brand logo is provided by the Pro add-on
- Fixed page rendering after the library updates: pages now display as crisp white paper (no grey tint or soft text)
- Hardened the PDF viewer’s error handling so a page that fails to render no longer stalls the rest of the book
- Raised page texture resolution for sharper text, with a lighter setting auto-applied to very large documents to keep memory in check
1.3.11
- Completed the output-escaping pass on the flipbook editor — the remaining conditional style and numeric-bound attributes are now escaped at output. No change to behaviour or appearance.
1.3.10
- Hardened output escaping across the admin and viewer templates — every dynamic value is now escaped at the point of output to meet WordPress.org review standards. No change to behaviour or appearance.
1.3.9
- Hardened output escaping on the editor’s Pro upgrade advert (logo and purchase link) to satisfy WordPress.org review standards
- Raised the minimum WordPress version to 6.2, matching the secure identifier placeholder used in the view-statistics queries
1.3.8
- Fixed collections (multi-PDF bookshelves) failing to display with a “no PDF URL provided” message — a shelf with one or more books now renders correctly
- Fixed the editor live preview overflowing its box when padding was increased — the preview now scales to keep the whole viewer inside the frame
- Book tabs in the viewer’s info panel now switch the displayed book, not just its information
- Added a reader keyboard and mouse shortcut reference to the editor’s Controls help sidebar
- Tidied a stray product label so the branding reads “Selytho” consistently
1.3.7
- Rebuilt the flipbook-editor “Pro Features” panel so the free build shows an upgrade advert in its place — no disabled or locked feature controls are present without the Pro add-on
- Completed the free/Pro split: all Pro feature defaults, saving, viewer output and the per-flipbook sound picker are now supplied exclusively by the Pro add-on, with the free build fully functional on its own
- Updated the bundled 3D engine library to a current maintained release
- Hardened the editor so it loads cleanly when the Pro add-on is not installed
1.3.6
- Security hardening for WordPress.org compliance: the view-tracking endpoint now verifies a request nonce, all view-statistics queries use fully prepared statements, and admin sidebar output is escaped through an allowlist
- No change to viewer behaviour or statistics
1.3.5
- Renamed the plugin to “Selytho Page Flip Creator” (removed the restricted “WP” term from the name, slug and text domain) for WordPress.org compliance
- Added a “Get Pro” link to the plugins-list row (shown on the free tier only)
- Made the soft page-curl a true Pro-only feature: the free build no longer contains any soft-cover rendering code, so soft is unavailable without the Pro add-on
- Removed the in-plugin Pro auto-installer and the licence-key entry from the free build; the upgrade screen is now advert-only, and all licence activation/status UI is supplied by the Pro add-on
- Rebuilt the Settings “Pro Features” card, the Soft flip-style option and the Sound option so the free build shows an upsell only — no disabled or locked controls
- Fixed flipbooks rendering as a tall, letter-boxed sliver inside block themes (constrained-layout width is now respected)
- Redesigned the upgrade overlay: clearer benefit bullets, a taller hero image, and added points about custom logos and removing the Selytho branding
- The “Created with Selytho Page Flip Creator” credit now links to the product page and reads consistently in the editor preview and on the front end
- Kept the plugin menu open with all items visible while editing a flipbook
- Removed unused bundled code (legacy viewer and the StPageFlip library) from the package
1.3.4
- Increased minimum width on select dropdowns to 110px so the selected option no longer crowds the chevron arrow
1.3.3
- Fixed native colour pickers (
<input type="color">) being squashed to a thin line under WordPress 7.0 — restored to a proper 48×30 swatch - Added a custom chevron arrow and right padding to select dropdowns so the arrow no longer overlaps the option text under WordPress 7.0
1.3.2
- Fixed Pro Features card “Upgrade” button and Licence card “Get Pro” button — both now open the in-plugin upgrade modal instead of navigating away to robsnow.eu
1.3.1

- Added Sound default toggle to Global Defaults in Settings

- Fixed large document overlay not showing in admin preview
- Fixed overlay re-appearing on refresh via sessionStorage confirmation
- Settings layout switched to CSS masonry columns
1.2.8
- Fixed sound not firing on every page turn — sound engine now clones Audio nodes per play so rapid flips never conflict
- Fixed same sound repeating consecutively — added no-repeat shuffle across the sound pool
- Updated page-turn sound effects
- Fixed PDF metadata not loading on media library select — fetchPdfMeta no longer triggers a redundant preview rebuild when called alongside loadPreview
1.2.7
- Fixed delete flipbook causing “headers already sent” warning by moving handler to admin_init
- Fixed Info Panel Branding card moved to top of column 3 in Settings layout
- Added fetchPdfMeta call on PDF select from media library (metadata loads without saving)
