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. AI detects repeated overlay text across pages - status stamps, evaluation marks, ownership notices, and similar annotations - and removes only the detected watermark cleanly, leaving surrounding content 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.
