New: Remove Watermark PDF Converter with AI

We've launched a new AI-powered Remove Watermark PDF converter that detects and removes text watermarks from PDF documents.

What's new

AI detects repeated overlay text across pages - status stamps, evaluation marks, ownership notices, and similar text annotations - and removes them cleanly without affecting surrounding content. Only the detected watermark is removed; other content stays unchanged. Watermarks in any language are supported, with an optional hint for unusual cases.

Parameters

  • AiDetection (bool, default True) - use AI to detect and remove text-based watermarks. When disabled, only structural watermarks embedded in the PDF are removed.
  • WatermarkHint (string) - optional description of the watermark to help the AI detect and remove it more accurately.
  • PageRange (string, default 1-2000) - limit processing to specific pages, e.g. 1-10 or 1,2,5.
  • Password (string) - password to open a protected PDF.
