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.
Cara Ia Berfungsi
Upload Your File
Select your NotebookLM-exported PDF, PPTX, or image file. Drag & drop is fully supported.
Auto Detection
The engine scans all pages and slides locally in your browser to precisely locate the NotebookLM watermark text and barcode pattern.
IDW Pixel Healing
Our advanced Inverse Distance Weighting algorithm seamlessly reconstructs the background — works on gradients, textures, and solid colors with zero visible artifacts.
Download Clean File
Download your fully clean PDF, PPTX, or PNG file instantly. No account needed. No waiting. No server uploads.
Ciri-ciri Hebat
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.
