How to remove the NotebookLM watermark

NotebookLM was renamed Gemini Notebook in July 2026. The watermark behaviour described here is the same under either name.

Where the watermark actually sits

It is placed in the bottom-right corner: a small product logo followed by the word “NotebookLM”. In every format it is burned into pixels rather than added as an object you could delete. A slide-deck PDF is a stack of full-page images with no text layer at all; a .pptx is the same images wrapped in slide XML; a video overview has it composited into the frames. That is why removal always means repainting the area, never deleting an element.

Option 1: strip it in the browser (free)

The watermark remover handles all three formats without an upload — it runs on WebAssembly inside the page, so your notebook contents never reach a server. What it does depends on the file you give it:

• Slide decks (.pptx) come out cleanest. There is no separate watermark object to delete — each slide is one full-bleed image with the badge baked in — so the badge is erased from that image. The slides are PNG, which is lossless, so the rest of the slide survives pixel for pixel.
• PDFs get an opaque patch drawn over the badge on every page, in a colour sampled from the paper beside it, so it blends into the page rather than showing as a white block. The page's own image is left untouched, so nothing is recompressed.
• Video overviews are re-encoded with the marked area reconstructed from the surrounding pixels. Expect a few minutes on a long overview and a small quality change, since every frame is redrawn.

Option 2: upgrade to Ultra

Google AI Ultra removes the watermark at the source, so exports come out clean with no post-processing and no quality loss anywhere. It is the only approach that leaves video untouched rather than re-encoded. Whether that is worth it depends on volume — for the occasional deck it is hard to justify, but if you are exporting client-facing video weekly, re-encoding every one of them gets old fast. See is NotebookLM free for what each tier actually changes.

Option 3: rebuild the export yourself

For slides and documents you can sidestep the watermark entirely by exporting the underlying content rather than the rendered file — copy the notebook text out and rebuild the deck or document in your own template. It is more work, but the result carries your own branding instead of a hole where someone else's used to be. Our export guides cover getting clean text and structure out first.

What none of these do

Removing the visible logo does not remove invisible provenance markers. Google embeds SynthID into AI-generated media, and that survives cropping, re-encoding and logo removal by design. A clean-looking file is still detectable as AI-generated, so none of this makes AI output pass as human-made — and presenting it that way is a good way to get caught.

People also ask

Is removing the NotebookLM watermark allowed?

It is your own content, generated from your own sources, so editing your export is ordinary use. What you should not do is present the result as something it isn't — AI-generated media stays AI-generated once the logo is gone.

Does the watermark remover upload my file?

No. It runs entirely in the browser using WebAssembly. Nothing is transmitted and nothing is stored, and it keeps working if you disconnect after the page has loaded.

Can the watermark still be selected as text in my PDF?

It should not be — these exports have no text layer, so there is nothing to select. If your PDF does have selectable text, it came from a different export path, and the patch will sit over that text rather than removing it.

Does removing the watermark reduce quality?

For slide decks, no — the badge is erased from the slide image and written back as PNG, which is lossless. For PDFs, no, since only a rectangle is drawn. For video, slightly: the file is re-encoded, so there is a small generational quality loss.
