NotebookLM Watermark Location, Size, and Why It's So Hard to Remove Manually

The NotebookLM watermark - also called the NotebookLM logo - sits in the bottom-right corner of every slide, is baked directly into the page's pixel data on PDF exports, and cannot be selected or deleted with a standard PDF editor because there is no separate watermark layer to target.

Before you can understand how to remove the NotebookLM watermark, it helps to understand exactly what you're dealing with. Where does it appear? How big is it? Why can't you just open your PDF in Preview or Adobe Acrobat and delete it? This article answers all of those questions with technical precision.

Where the Watermark Appears: Format by Format

On Slide Deck PDFs

The "Made with NotebookLM" watermark appears in the bottom-right corner of every slide page. It consists of a small rectangular element containing the NotebookLM logo (a small notebook icon) followed by the text "Made with NotebookLM" in a light-colored sans-serif font. The element sits approximately 2–3% of the slide width from the right edge and 1–2% from the bottom edge.

The watermark appears on every single page - there is no first-slide or last-slide exception. A 40-slide deck has 40 watermarked pages.

On PPTX Files

In PPTX exports, the watermark is embedded as a grouped shape element on the slide master. This means it technically is a separate element - unlike PDFs - and can be located in PowerPoint's Slide Master view. However, the shape is locked and may be located across multiple layout masters, requiring careful navigation to find and delete all instances. Our NotebookLM PPTX Watermark Remover finds and removes every instance automatically.

On Video Exports

The NotebookLM video watermark is more complex. It has two parts:

• Overlay logo: A semi-transparent "NotebookLM" text or logo that appears persistently in the bottom-right corner throughout the entire video duration
• Ending screen: A full-screen branded "Made with NotebookLM" screen displayed for approximately 2.5 seconds at the end of every Video Overview export

The ending screen is particularly intrusive for content creators because it appears on YouTube and social media as an unbranded outro that viewers see after the actual content ends. See our dedicated guide on how to remove the NotebookLM video watermark and ending screen for the full walkthrough.

Why the Watermark Is So Hard to Remove Manually

The Core Problem: NotebookLM Slides Are Image-Based PDFs

This is the most important technical fact to understand. When NotebookLM exports a slide deck as a PDF, it does not generate a standard PDF with text and vector elements. Instead, it rasterizes each slide into a bitmap image and embeds that image as a full-page PDF element.

The practical consequence is devastating for manual watermark removal: the watermark is not a separate layer, text object, or image element in the PDF structure. It is baked into the pixel data of the slide image. You cannot select it, cannot target it with a PDF editor's object selection tool, and cannot delete it as an isolated element.

Why PDF Editors Fail

Here is what happens when you try common PDF editing approaches:

• Adobe Acrobat "Edit PDF" mode: Cannot select or delete the watermark because it is inside the embedded image, not a separate PDF element
• Preview on Mac (Markup → Rect tool): Drawing a white rectangle over the watermark works visually but creates an obvious white patch - and changes the slide's visual design
• Photoshop content-aware fill: Works but requires exporting each page as an image, editing, and reassembling - hours of work for a 30-slide deck, and the fill quality varies depending on what is behind the watermark
• Online PDF watermark removers (generic): These tools target standard text/image watermarks that are separate PDF layers - they cannot detect or remove watermarks embedded inside the page image

Why the NotebookLM-Specific Removal Challenge

A purpose-built NotebookLM watermark remover works by knowing the exact characteristics of the watermark: its precise position on the page, its exact size in relation to the slide dimensions, and the mathematical properties of how it was composited onto the slide image.

With this knowledge, the tool can isolate the exact pixel region where the watermark exists and reverse the blending operation that placed it there - recovering the original slide pixels beneath. This is why a dedicated tool produces clean, lossless results where generic approaches produce blurry patches or obvious edits.

What Is "Made with NotebookLM" vs "Created with NotebookLM"?

Different NotebookLM export types use slightly different watermark text. Slide decks most commonly show "Made with NotebookLM" while some video outputs and audio overviews show "Created with NotebookLM." Both are functionally identical - same positioning, same purpose, same removal approach.

What This Means for You

If you've tried to remove the NotebookLM watermark manually and found it surprisingly difficult or impossible, you are not missing something obvious. The image-based PDF structure genuinely makes standard editing approaches ineffective. A tool built specifically for the NotebookLM watermark format is the only efficient solution - and it works whether or not the removal affects your slide quality is a concern for you (it doesn't).

Our free NotebookLM Watermark Remover is designed exactly for this task - it knows the watermark's precise characteristics and removes it cleanly, without any visible trace, in seconds.
