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

NotebookLM's exports are genuinely good — but every Video Overview, PDF report, and PPTX deck ships with a watermark in the bottom-right corner. In 2026 the watermark got bigger (it now measures roughly 179×40 pixels with its border on a 1600×900 export), which broke most of the older removal tools floating around.

Why most removers stopped working

Older tools hard-coded the watermark's position and size. When Google enlarged it, those fixed boxes started missing the mark — leaving half of the logo behind. Any tool you use today needs an adjustable removal region, not a fixed one.

The three formats need three different tricks

• ✦Video: the watermark is baked into the pixels, so it must be reconstructed from surrounding pixels (ffmpeg's delogo filter does this well).
• ✦PPTX slides: the watermark is just an embedded image repeated on every slide — it can be deleted from the file's XML with zero quality loss.
• ✦PDF reports: the watermark is drawn into the page, so the practical fix is covering it with a patch matched to the page background.

Do it locally — don't upload your files

Most watermark-removal sites upload your video to their servers. That's slow for big files and questionable for private content. Our NotebookLM Watermark Remover handles all three formats entirely in your browser: ffmpeg compiled to WebAssembly for video, direct XML editing for PPTX, and background-matched patching for PDF. Presets match the current 2026 watermark and the older smaller one, and the removal box is always draggable for whatever Google changes next.

Open the tool, drop your file, nudge the gold box if needed, and download the clean version. No upload, no signup, no cost.
