How to Remove the NotebookLM Watermark from Slides, PDFs & Videos (2026)

Google's NotebookLM places a small "NotebookLM" or "Created with NotebookLM" brand mark in the bottom-right corner of every exported slide deck, PDF, infographic, and video. If you need a clean file for a client meeting, a class presentation, or a portfolio, here is how to remove it — and what each method actually costs and preserves.

Where the watermark appears (and where it does not)

Key difference from Gamma: Gamma's watermark is a discrete, deletable object (a hyperlinked shape in PPTX, an image XObject in PDF). NotebookLM's mark is often flattened into the background pixels, which means structural deletion tools cannot always remove it — the approach depends on whether your specific export has the mark as a real object or a baked-in graphic.

Method 1: Browser-based removers (fastest)

Several free tools target NotebookLM exports specifically. They detect the fixed bottom-right position of the logo and reconstruct the background (gradient-aware fill), then return a clean file. For videos, they also trim the branded ending screen.

How to use one:

1. Open a NotebookLM watermark remover (examples: notebooklmremover.com, notebooklmremover.org).
2. Select your file type (PDF, PPTX, PNG, or MP4).
3. Drop the file in.
4. Download the cleaned version.

What it preserves: Text, layout, images, and formatting are untouched. The tool only modifies the watermark region.

Privacy: Most of these tools process files entirely in your browser using WebAssembly — no upload to any server. Check the tool's privacy policy to confirm before dropping in confidential documents.

Cost: Free.

Method 2: Manual editing (free, slower)

If you prefer not to use a third-party tool:

For PPTX exports where the mark is a real shape:

1. Open the .pptx in PowerPoint or LibreOffice Impress.
2. Check the Slide Master (View, then Slide Master / Master Slide).
3. If the NotebookLM logo appears as a clickable shape, select it and delete.
4. Close the master view and save.

This only works when the mark is a native PowerPoint object. If clicking it does nothing, it is flattened — use Method 1 instead.

For PDF exports:

1. Open in a PDF editor that supports object editing (Adobe Acrobat Pro, PDF-XChange Editor, or Sejda).
2. Use the "Edit PDF" or "Markup" tool to draw a rectangle over the bottom-right corner in a matching background color.
3. Flatten and save.

This covers the mark visually but does not delete the underlying pixels. It works for simple solid backgrounds but looks obvious on gradient backgrounds.

For video exports:

1. Trim the last 2-5 seconds to remove the branded ending screen.
2. Crop the bottom-right corner slightly to remove the persistent logo overlay — or use a video editor to place a matching-color rectangle over it.

For infographics (PNG): Crop the bottom margin, or use any image editor to clone-stamp or content-fill the logo area. Inpainting tools (Photoshop, GIMP, or free online inpainters) work well because the watermark sits over a predictable background region.

Method 3: Upgrade to Google AI Ultra ($125-250/month)

The official removal path. NotebookLM Ultra (part of Google's AI Ultra subscription tier) removes the watermark from slides, PDFs, and infographics. Video exports may still retain the branded ending screen.

Worth it if: You are a heavy NotebookLM user creating dozens of professional exports monthly. The plan also includes 50x higher usage limits and priority processing.

Not worth it if: You need a clean file once or twice. At $125+ per month, a free browser tool saves you $1,500+ per year.

Method 4: Avoid the watermark entirely

• Export as Audio Overview (MP3). Pure audio has no watermark. If your content works as a podcast or voice summary, this sidesteps the issue completely.
• Copy the content manually. Open the notebook, copy the generated text and data into your own presentation tool (Google Slides, PowerPoint, Canva). No watermark because you are creating a new file from scratch. Time-consuming for long decks but produces a fully original file.
• Use an alternative tool. Some AI study/presentation tools on free plans either have no watermark or have one that is easier to remove structurally. See our comparison of free tools without watermarks.

NotebookLM vs Gamma watermark: key differences

If you use both tools, you need different removal approaches. Gamma's watermark is always a separate file object, so tools like GammaRemover delete it structurally with zero quality loss. NotebookLM's mark is often pixel-embedded, so removal tools use region detection and background reconstruction — still effective but technically different.

Frequently asked questions

Does the Audio Overview have a watermark? No. Pure MP3 audio downloads from NotebookLM's Audio Overview feature have no visual or audible watermark. However, if you convert an Audio Overview into a video (Video Overview), the resulting MP4 gets the standard visual logo overlay and ending screen.

Can I just crop the watermark out? For images and simple PDFs, cropping the bottom margin works. For slides and video, cropping changes the aspect ratio and may cut into your content. A dedicated removal tool is cleaner.

Is it legal to remove the NotebookLM watermark? The watermark is service branding, not a copyright notice on your content. Removing it from material you created or own is generally treated the same as removing a "Made with [Tool]" tag from your own work. Do not remove branding from someone else's content to misrepresent its origin.

Can GammaRemover remove NotebookLM watermarks? GammaRemover is specifically built for Gamma's watermark structure (hyperlinked shapes and image XObjects). NotebookLM uses a different watermark format, so you need a NotebookLM-specific tool. For a guide covering multiple AI tools, see our AI watermark removal guide.

Will the watermark change in future updates? Possibly. Google updates NotebookLM frequently. Removal tools track these changes and update their detection. If a tool stops working after an update, check for a newer version.
