About the Stampfox
Stampfox helps Shopify merchants sell protected PDF downloads with automatic watermarking and personalized stamping. Upload your PDF files and create custom stamp templates using customer details like name, email, and order number. After checkout, buyers instantly receive their personalized stamped copy—never the original file. This protects your digital products from unauthorized sharing while adding a professional touch to every download. Control download access after refunds or cancellations, track each file delivery, and distribute through checkout, order status pages, email, or your storefront. Perfect for selling ebooks, guides, templates, and other digital content that needs protection and personalization.
