iframe and PDF.js Viewer are evenly matched on rating (4.4★ vs 4.4★) — the differentiator comes down to pricing fit, feature breadth, and which app's interaction pattern suits your team's workflow. Recommended evaluation path: install both apps' free tiers (where available) and run them in parallel on a small cohort of orders for 7-14 days before committing. The data tables below show the per-feature breakdown — for most merchants the deciding factor will be a single integration or workflow detail that's hard to compare from listing pages alone. This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical WordPress Plugin Directory listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.

iframe (4.4★, 56 reviews) and PDF.js Viewer (4.4★, 53 reviews) are essentially tied on rating. Look at review velocity and individual reviewer quotes — both visible on each app's detail page — to differentiate.
It depends on what you're optimizing for. iframe fits better if you prioritize broader integrations; PDF.js Viewer is the call if you need the larger user base. Read both apps' detail pages on AppRanks for the full feature breakdown, install counts, and recent listing changes.
Both apps are one-click installs from the WordPress Plugin Directory marketplace. iframe has more onboarding documentation maturity (56 reviews vs 53), which usually translates to better-tested setup wizards and quicker time-to-value. AppRanks doesn't measure setup time directly — read the recent reviews on each app's detail page for merchant-reported install experience.
iframe typically suits early-stage and growth-mode stores based on its review-base composition (56 reviews). PDF.js Viewer aligns more with early-stage and growth-mode stores (53 reviews). Larger review bases generally mean the app has been load-tested at scale — relevant if you're processing high order volume or handling enterprise compliance requirements.
Migration support varies by app and category. iframe and PDF.js Viewer both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from PDF.js Viewer" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
