Benefits
Why use this PPTX cleaner
The badge is in the same corner on every slide, so the work is the same on every slide — and it is done to the file you already have.
The deck stays editable
Only the slide’s background image is rewritten. Text boxes, speaker notes, animations and transitions are exactly the ones you exported.
One fixed corner, every slide
NotebookLM puts the badge in the same place at the same size, so page 8 is cleaned as carefully as page 1 — no per-page decisions.
Nothing to install
No Office add-in and no desktop app. Open the page, drop the file, download the result.
Frequently Asked Questions
What the conversion does, and what it deliberately leaves alone.
Does this work on NotebookLM PPTX exports?
Yes. It targets the “Made with NotebookLM” badge in the bottom-right corner of Slide Deck exports. Files up to 100 MB are supported, and both export shapes are handled: a badge baked into a full-page image is repaired, and a badge attached as a separate small shape is simply deleted — which is lossless.
How is this different from the PDF tool?
Same repair, different container. The PDF tool patches the rendered page; this one rewrites the slide images inside the .pptx, so the deck keeps its slides, notes and animations instead of becoming a stack of pictures.
Will the deck still open in PowerPoint, Keynote and Google Slides?
Yes. The package is rebuilt from the original parts, every non-image part is left byte-for-byte alone, and only the page images that carry the badge are rewritten: PNG pages are re-encoded losslessly, JPEG pages are re-encoded at high quality.
Does it change anything else on my slides?
No. The erase box sits in the bottom-right corner and is measured relative to the image, so no pixel outside it is written. The only visible difference is that corner.
What happens if the deck has no watermark?
Nothing is charged and nothing is changed. The tool samples several slides first; if it cannot find the badge it stops and tells you, rather than altering a deck that may be someone else’s design.
Is my file uploaded anywhere?
No. The file is read with the File API and processed on your device. Only aggregate counts — format, size bucket, success or failure code — are recorded, never the file or its contents.
