PDF watermarking for businesses

Watermarks that actually stay put.

Tile-shredded, randomized, AES-256 encrypted. Designed to survive every PDF editor, "unlock" tool, and clone-stamp attack. Built for the docs your business can't afford to lose control of.

How it works

Three layers of defense, one output.

Tile Shredding
No single object to delete

Standard watermarks exist as one image in the PDF — click, delete, done. We shatter every page into 80 JPEG tiles with randomized boundaries. The watermark spans dozens of tiles. Deleting any one leaves a visible hole in the document.

Randomized Grid Core
Defeats automated removal tools

We stamp your watermark across the entire page in a repeating grid. Every instance has random rotation, opacity, scale, and position. No two instances match — so template-based removal scripts, clone stamps, and AI-powered watermark removers have nothing consistent to work with.

AES-256 Encryption
Bank-level security

Every output is encrypted with AES-256 — the same standard banks and the US military use. Editing is blocked. Content extraction is blocked. Even "Print to PDF" tricks fail because printing permissions are revoked at the file level.

OCR-compatible

Your underwriters can still read it.

Most watermark tools cover documents so heavily that OCR engines, AWS Textract, and underwriting bots can't extract a single line of text. Ours are calibrated to stay fully readable — so merchant statements, contracts, and funding offers can still be analyzed downstream.

  • Works with Tesseract, AWS Textract, Google Document AI
  • Automatic OCR-safe opacity capping in tiled mode
  • Solid-background logos auto-cleaned so text isn't obscured
  • Branding visible to humans, invisible to analysis engines

Why us

Built for businesses tired of watching their documents get stripped.

Every day, brokers, lenders, and agencies send out branded documents — merchant statements, contracts, funding offers, proposals — only to watch them circulate without the watermark. A "PDF unlock" tool online is all it takes to erase a normal watermark in seconds. Mark My Merchant is the first watermarking service built to survive every known removal method.

The Problem

Standard PDF watermarks are a single image layer. A PDF editor can delete it in one click. Free online "unlock" tools strip encryption too. Once it's gone, your document circulates without any trace of who produced it — costing you leads, leverage, and deals.

Our Solution

We shatter every page into 80 randomized image tiles, stamp your watermark across the entire page in a non-uniform pattern, and encrypt the output with AES-256 so it can't be printed, edited, or extracted. No single object to delete. No repeating pattern to clone-stamp out.

Who Uses It
