NotebookLM PDF Cleaner

通过 python3 脚本为 NotebookLM 导出的幻灯片 PDF 生成新副本，在每页右下角绘制遮罩覆盖页脚徽标，默认遮罩参数会按页面尺寸自动缩放。保留原文件，输出 *-clean.pdf，支持 --inspect、--out、--mask-* 以及可选的元数据/注释剥离，明确不适用于通用水印移除。

description
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.pdf copy
  • 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.pdf

By default it writes:

/path/to/input-clean.pdf

Useful 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-annots

Safety checks

  • Refuse non-PDF input
  • Refuse overwrite of the source file
  • Refuse overwrite of an existing output unless --force is used
  • Keep metadata/annotation stripping off by default

Defaults

The default mask is tuned for common 16:9 NotebookLM slide-deck exports:

  • mask-x = 1208
  • mask-y = 0
  • mask-w = 168
  • mask-h = 32

These values are scaled automatically for each page size.

Recommended workflow

  1. Keep the original PDF
  2. Create *-clean.pdf
  3. Spot-check page 1 and one later page
  4. If needed, adjust the mask values and rerun
  5. Share or email the cleaned copy
