77 Quality Score

Active Installs

With 8,000 active installs, the plugin is a minor player compared to PDF Embedder at 300,000 and DearFlip at 200,000, so popularity is modest.

Update Freshness

The plugin was updated in February 2026 and is tested against WordPress 6.9.4, indicating a developer who keeps things current.

User Rating

14/15

The 90 out of 100 rating from 13 reviewers is strong, though the small sample size limits how much weight it should carry.

Support Health

8/15

Only one support thread exists and it has not been resolved, which is a yellow flag for anyone who expects active developer engagement.

WP Compatibility

15/15

Compatibility scores full marks thanks to the WordPress 6.9.4 test and a low minimum requirement of 3.6, though the absence of a stated PHP version is a small gap.

What It Does

Wonder PDF Embed lets WordPress site owners display PDF documents directly in pages and posts using Mozilla's PDF.js renderer. It produces responsive embeds and supports a lightbox viewing mode for inline PDFs without forcing users to download files. The plugin is geared toward sites that need to host reference documents, brochures, or reports alongside regular content.

Who It's For

This plugin is a good fit for small to mid-sized organizations that need a lightweight, no-frills way to embed PDFs on a WordPress site, particularly law firms, real estate agencies, educational institutions, and nonprofits sharing reports or brochures. Sites that have a handful of documents to display and do not need advanced features like flipbook effects or analytics will find it adequate.

Who Should Skip It

If you run a content-heavy site that needs thousands of embedded PDFs, advanced viewer skins, flipbook animations, or document analytics, look at DearFlip or PDF Embedder instead. Sites that rely on prompt support answers should also consider alternatives, since this plugin's single reported support thread remains unresolved.

The Bottom Line

Wonder PDF Embed scores 78.48 out of 100 and does the basic job of embedding PDFs reliably on WordPress. Its maintenance and compatibility are excellent, but the unresolved support thread and modest install base make it hard to recommend over PDF Embedder or DearFlip unless you specifically want a simpler, lighter alternative.

Pick DearFlip if you want flipbook-style page-turning animations and a far larger install base of 200,000.

PDF Embedder 86/100

Pick PDF Embedder if you need the most battle-tested option, with 300,000 installs and a long track record.

3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery 84/100

Pick 3D FlipBook if you want physics-based 3D page-flip effects for marketing brochures or product catalogues.

PDF Poster – Display PDF Files with Custom Viewer 80/100

Pick PDF Poster if you want to present each PDF as a poster-style thumbnail that opens in a custom viewer.

Embed Any Document – Embed PDF, Word, PowerPoint and Excel Files 79/100

Pick Embed Any Document if you also need to display Word, PowerPoint, or Excel files rather than PDFs alone.
