Automatically detect and remove redundant incrementally built slides from PDF presentations.
PrunePDF is a simple Python tool that cleans up PDF presentations by detecting and removing duplicate slides.
Teachers love exporting their incrementally built presentations as .pdf files without filtering. What should be 20-slide presentations can end up as a 100-slide PDF with 80 incremental duplicates.
This forces students to press the → key a bajillion times while navigating through repeated content.
Workflow
| Stage | Slide Count |
|---|---|
| Original presentation | 20 slides |
| Exported PDF | 100 slides (80 incremental duplicates) |
| After PrunePDF | 20 slides |
PrunePDF fixes these incremental exports, reducing clutter and making studying just a bit less painful.
