Smart PDF Watermarking for WooCommerce

Personalized PDF watermarks for every download.

Selling ebooks, guides, courses, or reports? Smart PDF Watermarking stamps each downloaded PDF with the buyer’s own details, so every copy is traceable to the customer who bought it. That makes shared files easy to trace and much less tempting to share.

No manual work. No file duplicates to manage. Your original PDF is never touched.

Watermark WooCommerce downloads automatically.

Pick a watermarks template on any downloadable product, and every customer download is watermarked on the fly.

• Per-download copies: each customer gets their own watermarked copy, generated at download time.
• Same file name: customers receive the file with its original name.
• Original untouched: the source PDF is never modified, and temporary copies are deleted automatically.
• Safe fallback: if a PDF can’t be watermarked, the customer still gets the file and you’re told why in the admin.

Dynamic watermarks with customer and order data.

Insert buyer details anywhere in a text watermark, with one click from a list of fields.

• Customer data: name, email, billing, and shipping details.
• Order data: order number, date, total, and more.
• Mixed with your text: for example, Licensed to {{o_billing_name}} – Order #{{o_number}}.
• Privacy first: passwords, keys, payment links, IP addresses and other sensitive data can never be printed.

A visual editor for text and image watermarks.

Design reusable watermark templates directly on a preview of a real PDF.

• Text watermarks: font, size, color, opacity, and rotation, with bundled fonts or your own TTF fonts.
• Image watermarks: logos and stamps from the Media Library, with transparent PNG support.
• Precise placement: nine position presets, exact pixel or percentage offsets, and repeated patterns across the page.
• Page targeting: all, odd, even, or specific pages, starting from any page.

Keeps your PDF intact.

The watermarked PDF stays as usable as the original.

• Links: web links and links to pages keep working.
• Bookmarks: the bookmarks panel is kept, with its full structure.
• Comments: notes, highlights, shapes, and stamps are kept.
• Restrictions: print, copy, and edit permissions of protected PDFs are kept.

Watermark your media library too.

Not only downloads: watermark the PDFs already on your site, one at a time or in bulk.

• Single PDF Watermarker: create a watermarked copy, or overwrite the original with an automatic backup.
• Bulk PDF Watermarker: select PDFs directly or by the posts and products they’re attached to.
• Auto apply: watermark PDFs automatically as they’re uploaded, based on rules you define.
• Backups and restore: restore any overwritten PDF from the Backups page.

MasterStudy LMS integration.

Selling courses? PDF course materials are watermarked with the logged-in student’s details each time they’re downloaded.

Deter sharing without changing how you sell.

Smart PDF Watermarking fits into your existing WooCommerce downloads. Set up a template once, assign it to your products, and every PDF your customers download carries their name.

Requires Ghostscript on your server to watermark PDF 1.5 and later, which covers most PDFs made by modern tools, plus the Imagick PHP extension for the editor previews. The plugin’s Settings page shows what your server has installed.
