Question 1

What is this tool?

Accepted Answer

An online tool that removes the "Made with NotebookLM" watermark from NotebookLM slide decks (PDF or PPTX) and Video Overviews (MP4). Everything runs in your browser.

Question 2

Do I need to install any software?

Accepted Answer

No. It works directly in Chrome, Edge, Safari and most mobile browsers — no plugin, no extension, no install.

Question 3

How much does it cost?

Accepted Answer

Processing is not charged. You only use credits when you download a finished file — 10 credits for a slide deck (PDF or PPTX), 20 for a video. Purchased credits never expire; bonus and free credits can expire after the period shown on the pricing page. See the pricing page for the current packs.

Question 4

Are my files safe?

Accepted Answer

Yes. Files are processed locally on your device with WebAssembly and are never uploaded to our servers.

Question 5

What file formats are supported?

Accepted Answer

PDF or PPTX for slide decks and MP4 for video overviews. These are the formats NotebookLM exports.

Question 6

How long does processing take?

Accepted Answer

Usually a few seconds. Because processing runs on your own device, the exact time depends on your hardware.

Question 7

Do NotebookLM and Gemini Notebook refer to the same search intent here?

Accepted Answer

People may use either name when searching for exported slides and videos. This independent tool is not affiliated with or endorsed by Google LLC.

Question 8

Can account plans or region affect visible watermark settings?

Accepted Answer

Platform features, plans and regional behavior can change. Check the official documentation for your account and location; this tool processes files you have already exported.

Question 9

Does this remove invisible watermarks or metadata?

Accepted Answer

No claim is made about invisible identifiers, provenance data or metadata. The tool is designed for visible page or video-frame content only.

Question 10

Can I process files that were not exported from NotebookLM?

Accepted Answer

No. The workflows are tuned for supported NotebookLM PDF, PPTX and MP4 export layouts. Use only files you own or are authorized to modify.

Question 11

What if a download fails, or I need the same file again?

Accepted Answer

Processing failures never cost credits — credits are only deducted when a download actually succeeds. Re-downloading the same processed result is free too: each result is charged once, no matter how many times you save it. Re-processing the file creates a new result, which counts as a new download.

Question 12

Is this only for NotebookLM PDF slides?

Accepted Answer

Yes. The cleaner is calibrated for the exact watermark placement in NotebookLM slide exports, which is why it works better than generic PDF editors.

Question 13

Will the text get distorted?

Accepted Answer

No. Only the watermark layer is removed — slides, text and images keep their original quality.

Question 14

What is the file size limit?

Accepted Answer

Up to 100MB per PDF file.

Question 15

Can I process multiple files?

Accepted Answer

Yes. As soon as one file finishes you can upload the next one and clean another deck.

Question 16

How long does it take?

Accepted Answer

Most 10–20 page decks are processed in under 5 seconds.

Question 17

Can I edit the text afterwards?

Accepted Answer

You get back a standard PDF: the pages look identical, but PDF is not an editable format. If you need to change the text later, run the original .pptx through our PPTX tool instead — it repairs the slide images in place, so the deck stays editable with its speaker notes and animations.

Question 18

Does the PPTX tool work on NotebookLM slide exports?

Accepted Answer

Yes. It targets the same bottom-right “Made with NotebookLM” badge on .pptx exports up to 100 MB. Both export shapes are handled: a badge baked into the full-page image is repaired, and a badge attached as a separate shape is deleted outright.

Question 19

Should I clean the PDF or the PPTX?

Accepted Answer

Pick the format you still have the source for. The PDF comes back as page images, so the text cannot be edited afterwards; the PPTX keeps its slides, notes and animations, so it stays editable in PowerPoint. If you only ever present the file, the PDF is enough.

Question 20

Do speaker notes, animations and transitions survive?

Accepted Answer

Yes. Only the slide images that carry the badge are rewritten; every other part of the package — XML, notes, media, theme — is left untouched.

Question 21

Will the cleaned deck still open in PowerPoint, Keynote and Google Slides?

Accepted Answer

Yes. The package is rebuilt from its original parts and the repaired images are re-encoded in their original format — PNG pages losslessly, JPEG pages at high quality. Nothing is added to the file, so there is no repair prompt on open.

Question 22

What is the file size limit for .pptx?

Accepted Answer

100 MB per file, the same as the PDF tool. Most NotebookLM decks are well under that.

Question 23

What if the deck has no watermark — do I lose credits?

Accepted Answer

No. Nothing is charged when no badge is found and the file comes back unchanged: the tool samples several slides first and stops rather than altering a deck it did not recognise.

Question 24

Is my video uploaded to your server?

Accepted Answer

No. All processing happens locally in your browser — the video never leaves your computer.

Question 25

Does it work with Audio Overview videos?

Accepted Answer

Yes. The tool is designed for the Audio Overview video format exported by NotebookLM, including the new ones.

Question 26

Does it reduce video quality?

Accepted Answer

No. Only the watermark area is re-encoded and the outro is trimmed; the rest of the video keeps its original visual quality.

Question 27

What happens to the outro animation?

Accepted Answer

The generic NotebookLM outro at the end is detected and trimmed automatically (roughly the last 2–3 seconds), so the clip ends on your content.

Question 28

Does this work with NotebookLM Video Overview MP4 exports?

Accepted Answer

Yes. The video workflow is designed for supported Video Overview MP4 exports processed locally in your browser.

Question 29

Why is the processed video shorter?

Accepted Answer

The workflow trims the ending card, so the completed file may be a few seconds shorter (typically about 2–3 seconds).

Question 30

Why does the first video processing run take longer?

Accepted Answer

Your browser may need to load the local video-processing engine on the first run. Later processing in the same session can start faster.

Question 31

What should I do if processing fails or the video is too short?

Accepted Answer

Confirm that the file is a supported MP4 export and keep the tab open. Very short videos may not have enough duration after ending-card trimming.
