About the Stampfox ‑ Sell PDFs
Stampfox helps Shopify merchants sell PDF downloads with automatic stamping and watermarking. Upload your PDF files and create custom stamp templates that include customer details like name, email, and order number. After purchase, buyers instantly receive a personalized stamped copy instead of the original file. This protects your PDFs from unauthorized sharing while giving you full control over access. Revoke downloads after refunds or cancellations, track every file download, and deliver stamped PDFs through checkout, order status pages, email, or your storefront. The Business plan supports multiple languages with different PDF files and emails per language.
Launched: May 18, 2026
