Customize & Protect PDFs with Watermarks & Passwords
What if you could tattoo PDF & EPUB files? You can! Ink ’em and make files more than look tough. For WordPress and other PHP websites.
Don’t just release your files into the wild — tag them first, so they don’t get lost!
Introducing PDF Ink
PDF Ink is a versatile tool that functions both as a WordPress plugin and a standalone PHP add-on. Customize PDF & EPUB files with watermarks at the time of download. Based on available data — such as WooCommerce, Download Monitor, or Easy Digital Downloads orders, or form submissions — add personalized content to your files, including visible or invisible text and images. Additionally, you can enhance security by adding encryption, file protection, and password features to PDFs.
PDF Ink is compatible with leading PDF libraries, including TCPDI, FPDI, FPDI PDF-Parser*, FPDF, TCPDF, and SetaPDF-Stamper*, for both PDF reading and writing needs.
As a replacement for several legacy plugins — including WaterWoo PDF, EDDiMark PDF, WooCommerce PDF Stamper, PDF Watermark for WooCommerce, PDF Stamper for Woo, EDDiStamper, DLM Stamper, and WP TCPDF Bridge, all trusted for over a decade — PDF Ink offers a comprehensive solution. If you’re an existing license holder, you can access PDF Ink by simply logging in and downloading the latest version.
*Optional 3rd party upgrades

More ways to try it
- Download PDF Ink Lite free from the WordPress repository. Lite is a very basic version of the plugin sold here, and will not work for all PDF files, or EPUB.
- Demo the libraries available for PDF Ink (try it out here)! Some PDF files will only work with FPDI-PDF Parser or SetaPDF-Stamper (paid library upgrades for PDF Ink). The demo will help you know if that’s what you need or not.
