Giới thiệu về công cụ này
The Batch Watermark Remover is a state-of-the-art PDF sanitizer that physically cleanses documents.
Generic watermark removers usually just overlay white blocks or distort document spacing. This tool utilizes a robust Content Stream Purge technique.
It parses the low-level rendering operators of each page, identifies specific watermark string commands (e.g. "Confidential", "DRAFT") or background image objects, and physically deletes or overwrites them. The watermarks disappear completely, preserving the original formatting and vector quality.
Trường hợp sử dụng

Remove expired "Confidential" or "Draft" watermarks for general public distribution.
Clearing background clutter
Scrub heavy background pictures that distract readers from scanning text.
Document reusing
Cleanse old page footer branding elements to apply new corporate templates easily.

If the watermark is stored as a separate text node or image XObject, the tool can isolate and physically wipe it.
No. The scrubbing engine only target operators matching the specified watermark signature; regular text remains untouched.
