Two Shopify apps for delivering digital files after purchase — one built specifically around secure PDFs, the other around a broad mix of digital products. Here's an honest, fact-checked look at how they line up.
PDF Products Pro is built specifically for merchants selling PDF files. It delivers each purchase automatically on three channels — email, the Shopify thank-you page, and the customer account portal — with no manual fulfilment and no theme edits. Its Enterprise plan adds per-buyer dynamic PDF watermarking (buyer name, email and order number) and advanced AI fraud protection, alongside IP restrictions, geolocation blocking, expiring links and per-order download limits. Every plan, including Free, includes 20GB of storage, unlimited downloads and no bandwidth caps.
According to its Shopify App Store listing, Sky Pilot lets merchants "sell, stream & protect digital products with a branded experience" — covering files, videos, audio, PDFs, license keys and link selling, with instant delivery through branded pages. Its listing describes security features including PDF/video stamping, download limits and timed access. Storage and monthly bandwidth are metered per plan, and video streaming, PDF stamping and license keys appear on its higher tiers. We describe Sky Pilot only from what its public listing states.
