NotebookLM PDF Slide Watermark Remover

How it works

Each page is rendered to a canvas, the watermark region is inpainted (OpenCV Telea or a fast color fill), and the pages are rebuilt into a new PDF as images.

NOTES / FAQ

Questions about this format

Are files uploaded to a server?

No. Every processing engine and all file data run inside your browser.

Can I still select or search text afterward?

No. Pages are rebuilt as images, so text becomes non-selectable and non-searchable.

Why rebuild as images instead of editing the PDF?

It guarantees the watermark is gone on every page no matter how the PDF was authored, without sending your file anywhere.

Which watermark position does it target?

The bottom-right area of each slide; adaptive mode adjusts for portrait slides.
