What the NotebookLM watermark actually is
It is a visible badge — a four-point sparkle followed by the words "Created with NotebookLM" — that Google stamps onto the lower right of exports from the free and AI Pro tiers. It is burned into the pixels of the finished file rather than stored as a separate layer or a metadata field, which is why no PDF reader or video player offers you a way to switch it off. Exactly where it lands differs by format: on documents and images it sits in the bottom-right corner, while on video it rides a band roughly two-thirds of the way down the frame.
Where it lands and how large it is depends entirely on which export you asked for:
| Export | Where the mark sits | Size and detail |
|---|---|---|
| Video Overview, 1080p | Lower right band, about two-thirds down the frame — not the bottom edge | x=1104, y=656, 770 × 62 px (57.5–97.6% across, 60.7–66.5% down), plus a 2.5-second "Made with Google" end card |
| Video Overview, 720p | Lower right band, same position in relative terms | x=736, y=437, 513 × 41 px — one relative rectangle serves both resolutions |
| PDF slide deck | Bottom-right of every page | A text badge rendered into the page itself; there is no object to select and delete |
| PPTX | Bottom-right of the slide artwork | Baked into the raster media under ppt/media/, not into the slide XML |
| Infographic (PNG / JPG / WebP) | Bottom-right corner | Located by scanning a corner box of at least 350 × 80 px, which grows on larger images |
| Gemini image | Bottom-right sparkle, no wordmark | 48 px mark inset 32 px from each edge; 96 px inset 64 px once the shorter side passes 1024 px |
| Audio Overview | Nowhere — there is no mark | No logo, no stamped disclaimer. What people mean is the hosts’ scripted greeting (10–20 s) and sign-off (10–15 s) |
The wording changed; the badge did not
Google renamed NotebookLM to Gemini Notebook on 16 July 2026, so newer exports increasingly read "Created with Gemini Notebook" where older ones read "Created with NotebookLM". Nothing else moved — same corner, same dimensions, same rendering path.
That matters for how detection is written here. The engines target the shape and position of the badge, not the letters inside it, so both wordings go through identical code and the rename required no change on the day it happened. The badge marks free and AI Pro output specifically; Google removes it at generation time for AI Ultra subscribers, which is the only sanctioned route to an unbranded export.
Which NotebookLM watermark remover handles which file
Choose by the file sitting on your disk, not by what you made in Gemini Notebook. A Video Overview downloaded as an MP4 and the same overview exported as a PDF deck carry the same badge but need completely different engines to remove it.
An MP4 from a Video Overview → Video watermark remover
FFmpeg's delogo filter paints over a fixed rectangle in every frame and trims the end card. The coordinates are preset rather than detected, so 1920 × 1080 and 1280 × 720 land exactly and other resolutions miss.
A PDF slide deck → PDF slide remover
Each page is re-rendered at 2× and rebuilt as a JPEG page. The layout survives; the selectable text does not. Read that limit before running it on a deck someone needs to search or quote.
A .pptx file → PPTX remover
Only the raster files under ppt/media/ are rewritten. Slide XML, speaker notes, animations and masters are repacked untouched — so if you have both a PDF and a PPTX of the same deck, use the PPTX.
A NotebookLM infographic → Infographic remover
Connected-component analysis finds the badge, then the gap is filled with a vertical ramp sampled from an 8 px strip above and below it. Flat template backgrounds close invisibly; photographs behind the corner do not.
An image generated by Gemini or Nano Banana → Gemini sparkle remover
A different mark and a different method entirely. The sparkle is alpha-blended, so the pixels underneath can be solved for rather than repainted: original = (watermarked − α × 255) / (1 − α).
An MP3 or M4A Audio Overview → Audio intro/outro trimmer
There is no badge to remove. The NotebookLM podcast trimmer cuts the greeting and sign-off using FFmpeg stream copy, so nothing is decoded or re-encoded and the bitrate comes out identical to the source.
Any image carrying EXIF, GPS or C2PA data → Image metadata remover
Unrelated to watermarks. The file is decoded to a canvas and re-encoded from pixel data only, which drops every metadata block — including GPS coordinates and Content Credentials — while leaving the dimensions unchanged.
Two of those take the same file type, so here is how to tell them apart. Open the image and look at the corner: a sparkle with a wordmark next to it is a NotebookLM infographic and goes to the infographic remover, which fills the area in. A bare four-point sparkle with no text at all is a Gemini generation and goes to the Gemini remover, which inverts the blend instead. Sending a file to the wrong one leaves the mark in place.
Why the NotebookLM watermark remover never uploads your file
Nothing is uploaded because there is nowhere to upload it to. This is a static site served from a CDN with no upload endpoint, no processing queue and no server-side code that touches files — so privacy here is a property of the architecture rather than a promise you are asked to believe.
Check it yourself in about thirty seconds
Press F12, open the Network panel, and drop in a file. You will watch the page assets load once — the FFmpeg WebAssembly core for video and audio, pdf.js and pdf-lib for PDFs, JSZip for PPTX, two small alpha template PNGs for Gemini images — and after that, no request carrying your file.
There is a stronger version of the same test. Let the page finish loading, disconnect from the network entirely, then process a file. It still works, because by that point everything the NotebookLM watermark remover needs is already in the tab.
What is actually doing the work in the NotebookLM watermark remover
None of this is our invention. Video and audio run FFmpeg compiled to WebAssembly, self-hosted here rather than pulled from a third-party CDN. PDFs are rendered by pdf.js and reassembled by pdf-lib. PPTX packages are unzipped, edited and rezipped by JSZip. Images go through the browser's own Canvas API.
They are the same open-source libraries a desktop tool would use, compiled to run inside a browser tab instead of on a server.
What this architecture costs you
Speed, and sometimes memory. x264 running in WebAssembly has no GPU path, so a ten-minute 1080p video routinely takes longer to process than it takes to watch, and a 100-page deck can exhaust memory on a phone before it finishes.
A server would be faster. It would also mean your file leaving your device, a queue it sits in, and a retention policy you would have to take on trust. What the site itself logs is set out on the privacy page.
What this site will not do
Four things this site is regularly assumed to do and does not. Stated here rather than buried in a footer, because knowing them may change whether you bother running your file at all.
It does not remove SynthID or any invisible watermark
SynthID is embedded into the pixel signal during generation — and into the audio waveform — rather than layered on afterwards. Google designs it to survive cropping, resizing, filters, screenshots and lossy re-compression, so clearing a corner leaves it completely intact.
The practical test is easy to run against you: anyone can upload your cleaned file to the Gemini app and ask whether it was made with Google AI. Removing a visible badge changes how a file looks. It does not make it undetectable as AI-generated, and a tool advertising one-click SynthID removal is either confusing the two watermarks or overstating what it does.
It does not bypass DRM, paywalls or access controls
Every engine here operates on a file already sitting on your disk, that your own software can already open. Nothing decrypts protected content, defeats a licence check or unlocks a paid tier. If a file will not open on your machine, it will not open here either.
It does not change who owns anything
The badge is a service credit for the generation tool, not a copyright notice on the content. Taking it off neither transfers nor creates any right in the material — and that cuts both ways. If the sources behind an export were not yours, a clean corner changes nothing about that, and the attribution you owed before is the attribution you owe after.
It is not a Google product
NotebookLM Remover is an independent project, not affiliated with, endorsed by or sponsored by Google. NotebookLM, Gemini Notebook, Gemini and SynthID are trademarks of Google LLC. Google's own route to an unbranded export is a Google AI Ultra subscription, which strips the branding at generation time instead of afterwards — the comparison of the free and Ultra tiers covers what that costs and what else it changes.
Is removing the NotebookLM watermark allowed?
For an export you generated yourself, from sources you are entitled to use, removing the badge is generally treated as ordinary editing. It is a branding overlay, not a technical protection measure, and taking it off circumvents no access control. That is the situation most people are in, and it is the uncomplicated one.
Where it stops being straightforward
It is not a licence to strip attribution from work that is not yours. Removing the mark from someone else's export so the result reads as your own is the one use we ask you not to make of this site. Separately, Google's terms govern what you may do with Gemini Notebook output regardless of what a post-processing tool can technically achieve — the question of whether a mark can be removed is not the question of whether it should be.
Disclosure is a separate obligation from the badge
Platforms and, increasingly, regulators require AI-generated or materially altered content to be labelled when it is published, and that duty attaches to the person publishing it rather than to how the file looks. YouTube asks creators to disclose realistic synthetic content. Academic honesty policies usually want a declaration in a specific place and a specific form. A clean corner satisfies none of that, and since SynthID stays embedded either way, a cleaned export remains verifiable as Google output.
None of the above is legal advice, and none of it is specific to your jurisdiction or your contract. It is a description of what the NotebookLM watermark remover does and what it leaves untouched. The longer treatment is in our article on the legality of removing the NotebookLM watermark, and the limits we place on using this site are written out on the acceptable use page.
