How to Remove a NotebookLM Watermark: Choose the Right Export Format

NotebookLM can create Slide Decks and Video Overviews from your sources. The file you download determines the right workflow: a PDF Slide Deck, a PowerPoint .pptx, and a Video Overview MP4 are different file types. This guide helps you choose the appropriate local-browser tool for files you own or are authorized to modify.

Choose your downloaded file

| If you downloaded… | Use this workflow | What you receive | | --------------------------------- | ----------------------------------------------- | ------------------------------------------------------ | | A Slide Deck PDF | PDF Slide Deck tool | A processed PDF | | A PowerPoint .pptx presentation | PPTX Slide Deck tool | A processed .pptx file | | A Video Overview MP4 | Video Overview tool | A processed MP4 with the supported ending card trimmed |

Choose the file extension, not a generic label such as “slide” or “video.” Processing the wrong format can produce an unusable result.

PDF Slide Decks

Use the PDF workflow when NotebookLM exported the deck as a PDF. The tool processes the visible badge area on each supported page locally in your browser; your source file is not uploaded to our servers. Downloading a completed result uses 10 credits.

PDF is the practical choice when you need a presentation-ready document. See the full PDF Slide Deck guide for supported input and privacy details.

PPTX presentations

Use the PPTX workflow only when you downloaded a real .pptx file. The tool handles the supported slide image or badge structure in the browser and returns a new PowerPoint file. Downloading a completed result uses 10 credits.

PPTX is the better route when the original deck still needs to be opened in PowerPoint, Keynote, or Google Slides. See the PPTX Slide Deck guide before processing a presentation with unusual slide layouts.

Video Overview MP4s

Use the video workflow for a NotebookLM Video Overview MP4—not an Audio Overview. It targets supported visible frame content and can trim the standard ending card locally in your browser. Downloading a completed result uses 20 credits.

Video processing time depends on the duration, resolution, browser, and device. Read the Video Overview guide for the supported scope before starting.
