- Create a presentation-ready copy of a NotebookLM-exported slide-deck PDF by masking the small visible NotebookLM footer badge at the bottom-right of each page. Use when the user wants a cleaner NotebookLM PDF export for sharing, presenting, or emailing. This skill is narrowly scoped to NotebookLM slide-deck PDFs and does not act as a general watermark-removal tool.
NotebookLM PDF Cleaner
Use this skill for NotebookLM slide-deck PDFs that contain the small visible NotebookLM footer badge in the bottom-right corner.
Default behavior
The default behavior is intentionally narrow and safe:
- keep the original PDF unchanged
- write a new
*-clean.pdfcopy - mask the small bottom-right NotebookLM footer area on each page
It does not remove arbitrary watermarks or redesign slides.
Script
python3 {baseDir}/scripts/clean_notebooklm_pdf.py /path/to/input.pdfBy default it writes:
/path/to/input-clean.pdfUseful flags
# Explicit output path
python3 {baseDir}/scripts/clean_notebooklm_pdf.py in.pdf --out out.pdf
# Inspect only (no output file written)
python3 {baseDir}/scripts/clean_notebooklm_pdf.py in.pdf --inspect
# Tune the bottom-right footer mask in PDF points (origin = bottom-left)
python3 {baseDir}/scripts/clean_notebooklm_pdf.py in.pdf --mask-x 1208 --mask-y 0 --mask-w 168 --mask-h 32
# Optional advanced hygiene flags
python3 {baseDir}/scripts/clean_notebooklm_pdf.py in.pdf --strip-metadata --strip-annotsSafety checks
- Refuse non-PDF input
- Refuse overwrite of the source file
- Refuse overwrite of an existing output unless
--forceis used - Keep metadata/annotation stripping off by default
Defaults
The default mask is tuned for common 16:9 NotebookLM slide-deck exports:
mask-x = 1208mask-y = 0mask-w = 168mask-h = 32
These values are scaled automatically for each page size.
Recommended workflow
- Keep the original PDF
- Create
*-clean.pdf - Spot-check page 1 and one later page
- If needed, adjust the mask values and rerun
- Share or email the cleaned copy
