How to Remove NotebookLM Watermark from Slides, Video & PDF (2026)

Why Does NotebookLM Add Watermarks?

Google NotebookLM is one of the most powerful AI research tools available today. It can turn your notes, documents, and sources into polished slideshows, video summaries, PDF reports, and infographics — all with a few clicks. There's just one catch: every export gets stamped with a "Made with NotebookLM" watermark.

This watermark appears in different places depending on the format:

• Video exports — a persistent logo overlay in the bottom-right corner, plus a branded end card ("Made with Google") in the last few seconds
• PDF slides — a small "NotebookLM" text badge on each rendered slide page
• PPTX exports — an embedded watermark image inside each slide
• Infographics — a "NotebookLM" stamp in the bottom-right area

Google does offer a way to remove these watermarks natively: NotebookLM Ultra, priced at $250/month (part of the Google AI Ultra plan). For enterprise teams with a budget, that works fine. But for students, freelancers, educators, and solo creators, paying $3,000 a year just to remove a logo is absurd.

So what are your actual options? Let's walk through four methods — from the fastest free tool to the manual workarounds.

Method 1: Use NotebookLM Remover (Recommended)

NotebookLM Remover is a free, browser-based tool built specifically for removing watermarks from NotebookLM and Gemini exports. It handles every format NotebookLM can produce — video, PDF slides, PPTX, and infographics.

The key selling point: everything runs 100% in your browser. Your files never leave your device. There's no upload to a server, no account required, and no file size limits. It uses Canvas API, FFmpeg WebAssembly, and pdf.js to process everything locally.

Removing Watermarks from NotebookLM Videos

NotebookLM video exports have two watermark elements: a persistent logo overlay during the video and a "Made with Google" end card in the final 2–3 seconds. The video remover handles both automatically.

1. Go to notebooklmremover.org/video
2. Drop your exported MP4 file onto the upload zone
3. The tool detects the video resolution (1080p or 720p) and applies the correct watermark coordinates
4. It trims the branded ending and removes the logo overlay using FFmpeg WASM
5. Optional: adjust FPS (15 or 30) or apply a cinematic color grade
6. Download your clean video — done

Processing time depends on the video length and your device, but most 5-minute clips finish in under 60 seconds on a modern laptop.

Removing Watermarks from PDF Slides

When NotebookLM exports a slide deck as PDF, each page gets a watermark badge. The PDF remover renders each page at 2x resolution, removes the watermark using pixel-level detection, and rebuilds a clean PDF.

1. Go to notebooklmremover.org/slides
2. Upload your PDF file
3. Each page is processed automatically — you can preview the results in a scrollable viewer
4. Download the rebuilt PDF or individual page images

Removing Watermarks from PPTX Files

PPTX exports embed the watermark as an image layer inside each slide. The PPTX remover unpacks the file, processes the embedded images, and repacks a clean PPTX that you can open in PowerPoint or Google Slides.

1. Go to notebooklmremover.org/pptx
2. Upload your .pptx file
3. The tool unzips the file, processes watermark images, and rebuilds it
4. Download the clean PPTX — all your animations, text, and layouts are preserved

Removing Watermarks from Infographics

NotebookLM infographics are exported as PNG or JPG images with a text watermark in the bottom-right corner. The infographic remover uses connected-component analysis to detect the watermark region and fills it with a smooth gradient sampled from the surrounding area.

1. Go to notebooklmremover.org/infographic
2. Upload your infographic image
3. The watermark is detected and removed in under a second
4. Preview the result and download

Bonus: If you're working with Gemini-generated images (which have a sparkle "✦" watermark), there's a dedicated Gemini image remover that uses alpha-channel reversal for lossless removal on standard sizes.

Method 2: Manual Removal in PowerPoint

If you only have a few PPTX slides and don't mind tedious work, you can remove watermarks manually:

1. Open the PPTX in Microsoft PowerPoint
2. Go to each slide and look for the watermark element — it's usually an image layer or text box
3. Click on the watermark and delete it
4. Repeat for every single slide
5. Save the file

Downsides:

• Extremely tedious for decks with 20+ slides
• The watermark may be embedded in the slide master, requiring you to edit the template
• Doesn't work for video, PDF, or image formats at all
• Easy to miss watermarks if they're layered behind other elements

This method is viable for a one-off 5-slide deck, but impractical for anything larger. And if your export is a video or PDF, you'll need a different approach entirely.

Method 3: Google Slides AI Eraser

Google Slides has introduced an AI-powered "Magic Eraser" feature that can remove objects from slide backgrounds. Some users have tried using this to erase NotebookLM watermarks.

How it works:

1. Import your PPTX into Google Slides
2. Select the background image on each slide
3. Use the AI eraser tool to paint over the watermark area
4. The AI attempts to fill in the removed region

Why it's unreliable:

• The AI eraser is designed for photos, not text overlays on designed backgrounds — it often produces visible smudging or artifacts
• It only works on rasterized images, so text-based watermarks in the PPTX layer structure aren't affected
• Results vary wildly depending on the background complexity
• Doesn't work for video or PDF exports
• Requires a Google Workspace account with access to the AI features

If you're in a pinch and only have one or two image-heavy slides, it might work. But for consistent, artifact-free results across all formats, a purpose-built tool like NotebookLM Remover is far more reliable.

Method 4: Upgrade to NotebookLM Ultra

The "official" way to export without watermarks is to subscribe to Google's AI Ultra plan, which includes NotebookLM Ultra among other premium AI features.

What you get:

• Watermark-free exports in all formats
• Higher usage limits and priority processing
• Access to Gemini Ultra features across Google products
• 2TB of Google storage

What it costs:

• $250/month (or $2,500/year if billed annually)
• This is part of the Google AI Ultra bundle — you can't buy NotebookLM watermark removal separately

For enterprise teams already paying for Google Workspace, bundling this in might make sense. For students, educators, freelancers, or anyone making occasional exports, spending $250/month to remove a small logo is hard to justify — especially when free alternatives exist.

Which Method Should You Choose?

Method	Formats	Cost	Speed	Quality
NotebookLM Remover	Video, PDF, PPTX, Images	Free	Seconds to minutes	Excellent
Manual PowerPoint	PPTX only	Free	Slow (manual)	Good (if careful)
Google Slides AI Eraser	Images in slides only	Free (with Workspace)	Moderate	Inconsistent
NotebookLM Ultra	All formats	$250/month	Instant (no watermark)	Perfect

Bottom line: If you want a fast, free solution that works across all formats and keeps your files private, NotebookLM Remover is the clear winner. Manual methods work in a pinch for PPTX but don't scale. Ultra is the premium option for teams with budget.

Frequently Asked Questions

Is it legal to remove NotebookLM watermarks?

Yes. The watermark on NotebookLM exports is a branding element, not a copyright protection mechanism. You created the content using your own sources, and Google's Terms of Service do not prohibit removing the watermark from your own exports. Removing it for personal, educational, or professional use is perfectly fine.

Is NotebookLM Remover safe to use? Do my files get uploaded?

Your files never leave your device. NotebookLM Remover processes everything 100% in your browser using client-side technologies (Canvas API, FFmpeg WebAssembly, pdf.js). There is no server upload, no account required, and no data collection. You can verify this by checking your browser's network tab — zero outbound requests during processing.

Does it work on all NotebookLM export formats?

Yes. NotebookLM Remover supports all export formats that NotebookLM produces: MP4 videos, PDF slide decks, PPTX presentations, and PNG/JPG infographics. It also supports Gemini-generated images with the sparkle watermark. Each format has a dedicated processing engine optimized for that specific watermark type.

Is there any quality loss after removing the watermark?

For images and infographics, the removal uses pixel-level detection and gradient fill — the result is visually indistinguishable from a clean export. For PDFs, pages are rendered at 2x resolution before processing, so quality is preserved. For videos, the output quality matches the input — you can choose to keep the original FPS or adjust it. Gemini images using the alpha reversal method have zero quality loss (mathematically lossless).
