The best Shopify eBook apps for 2027

How did we compare the apps?

• Protection inside the file: does each buyer get a personal copy, and for which formats?
• Tracing: can a shared file be traced back to an order?
• Book quality: does the app check how the EPUB looks on e-readers before you sell?
• Delivery: thank-you page, email, download limits, link expiry.
• Price model: monthly plan, fee per sale, prepaid credits or share of sales.

The apps at a glance

Facts from each app’s Shopify listing or website, retrieved 7 November 2026 (Miguel 4 November 2026). “Not named” means the source does not mention it. Prices in US dollars per month unless stated, without tax. The price models differ, so compare them for your own sales volume.

Pageseal: personal copies of eBooks, PDFs and audiobooks

Every sale becomes a personal copy: a note page with the buyer’s name and order number and a hidden identifier that stays without the note page. EPUBs, including fixed layout, are checked on Apple Books, Android and Kindle before you sell. Download on the thank-you page and by email. Plans: Free ($0 a month, first 5 copies free once, then $0.75 per copy), Starter ($15 a month, 40 copies included, then $0.69), Pro ($79, 200 copies, then $0.59) and Scale ($299, 1,500 copies, then $0.49).

LemonInk: prepaid watermarking with MOBI and LCP

LemonInk signs EPUB, MOBI and PDF files “visibly and invisibly” and covers all formats of a book with one credit. Credits are prepaid, from $0.25 per watermark at volume, with 5 free credits at sign-up. Readium LCP encryption is in an invite-only beta. Pageseal vs LemonInk.

Sky Pilot: digital downloads with video streaming

Sky Pilot delivers files, videos, links and license keys on branded download pages and streams video. PDF and video stamping are part of the Growth plan at $54.99 a month; there is a free plan with 100 MB. Pageseal vs Sky Pilot.

SendOwl: its own checkout, also outside Shopify

SendOwl sells digital products through Shopify and its own checkout, with PDF stamping, expiring links and download limits on every plan from $39 a month (7-day trial, no free plan). Pageseal vs SendOwl.

Filemonk and Imprint Files: PDF stamping

Filemonk adds PDF watermarking from its Lite plan at $10 a month. Imprint Files stamps PDFs with the buyer’s details and offers invisible marks and leak search in its Premium plan at $18.99 a month. Neither names EPUB stamping in its listing.

Miguel: watermarked EPUB with a share of sales

Miguel watermarks EPUB, MOBI and PDF and charges 10% of the products sold through the app; its listing says charges may be billed outside the Shopify invoice.

Shopify Digital Products: free and simple

Shopify’s own app attaches files or links to products and sends access links after purchase, with access limits. It names no watermark. Pageseal vs Shopify Digital Products.

BookFunnel: author delivery with reader support

BookFunnel is not a Shopify app but delivers Shopify sales through an integration. Direct sales delivery with watermarked EPUBs starts with the Mid-List plan ($20 a month or $200 a year). Its strengths are reader help, reader magnets and review copies. Pageseal vs BookFunnel.
