NotebookLM stamps a small “NotebookLM” wordmark onto the files it generates — usually in a corner of every slide, PDF page or image. When the content is yours, you can take that logo off in a few clicks without installing software or sending your files to a server. This guide shows exactly how, and why the whole process stays private on your own device.
Remove the watermark in 5 steps
-
1 · Export your file from NotebookLM
Open your notebook and export the slides, PDF or image you want to clean. The “NotebookLM” logo is baked into the exported pixels, which is why it can’t simply be switched off — it has to be edited out afterwards.

2 · Open the Wiper NotebookLM remover
Go to the NotebookLM watermark remover. It loads instantly in your browser — there is no sign-up, no install and no upload step to wait for.
-
3 · Drop in your file
Drag your PDF, PPTX or image onto the drop zone, or click to browse. Everything is processed locally on your own device using WebAssembly and Canvas — the file never travels over the network.
-
4 · Let it auto-detect and clean
The tool locates the “NotebookLM” logo by contrast analysis and reconstructs the area from the surrounding background (inpainting), rather than pasting a box over it. You see a before/after preview right away and can brush over anything that remains.

5 · Download the clean result
Save the cleaned file in the same format. For PDFs the page is rasterized during cleaning, so selectable text becomes an image — keep a fresh export if you still need the text layer.
Why it stays private
Because the work happens on your device, your files never leave your computer — you can even disconnect from the internet after the page loads and it keeps working. Wiper edits the visible logo only; invisible provenance marks such as SynthID are never touched, and it is not affiliated with Google.

FAQ
Is it legal to remove the NotebookLM watermark?
Only remove it from content you created or have the rights to edit. Google states that you own the content NotebookLM generates for you, but you remain responsible for how you use the cleaned files.
Do my files get uploaded anywhere?
No. All processing runs in your browser using WebAssembly and Canvas. Your slides, PDFs and images never leave your device.
Will the watermark always come off cleanly?
On plain or gradient backgrounds the logo reconstructs almost invisibly. On busy backgrounds a faint trace can remain — brush over it and reprocess for a cleaner result.
