What is the NotebookLM Watermark?

Ako to funguje

Auto Detection

Skvelé funkcie

PDF Multi-Page Cleaning

Renders each PDF page at 2x resolution, precisely detects watermark coordinates via PDF.js text extraction, and heals the canvas pixel-by-pixel before recompiling to a clean PDF.

PPTX Template-Level Removal

Cleans watermarks from PPTX slide XML, slide layouts, and slide master templates. Catches picture-based watermarks via alt-text matching — even when there's no selectable text.

Image & Slide Background Healing

Heals watermarks from standalone JPG/PNG/WebP images and from embedded slide background images inside PPTX archives using IDW canvas inpainting for flawless results.

Smart Barcode Pattern Detection

NotebookLM watermarks include a vertical barcode-like separator to the left of the text. Our engine accounts for its full width with expanded padding to capture it 100% cleanly.

100% Private & Local

No file is ever sent to any server. All processing runs entirely inside your browser using JavaScript Canvas APIs. Your documents stay completely private.

Cross-Platform Browser Support

Works on all modern browsers — Chrome, Firefox, Safari, Edge — across Windows, Mac, Android, and iOS. No extensions or plugins required.
