What is the NotebookLM Watermark?

When you export a PDF or PPTX presentation from Google NotebookLM, a subtle transparent watermark and barcode pattern is automatically added across your pages and slides.

Our NotebookLM Watermark Remover scans your document locally inside your browser and cleans the watermark with zero quality loss — keeping your privacy intact.

Moćne značajke

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.
