Yes, it is completely free. We do not charge for document watermark removal, and there are no hidden subscription plans.
Which file formats are supported?
We fully support PDF (.pdf) documents and Microsoft PowerPoint (.pptx) presentation decks.
Are my documents secure?
Absolutely. Everything runs 100% client-side inside your browser sandbox. No file is ever uploaded to a server, keeping your data completely confidential.
Does it modify the layout or fonts?

What is the NotebookLM watermark barcode pattern?
NotebookLM exports include a vertical barcode-like line separator (||||||||) to the left of the "NotebookLM" text in the bottom-right corner of every page and slide. Our engine accounts for this wider pattern and uses expanded horizontal padding to capture it 100% cleanly.
