NotebookLM PDF Watermark Remover — Features
Remove watermark from every page
100% browser-local, no upload
Keep visual PDF page layout
The NotebookLM PDF Slides Watermark Remover is designed to clean PDF presentations generated by Google NotebookLM. The tool uses PDF.js to render each page to canvas, detects the "Created with NotebookLM" watermark area as image content, uses gradient fill to restore the background, and rebuilds an image-based PDF with pdf-lib. The entire process happens in your browser without uploading files. The output keeps the visual page layout, but it does not preserve selectable text, font objects, links, or vector content from the original PDF. Large PDFs may fail due to browser memory limits; for best results, use NotebookLM slide deck PDFs under 50MB.
