A lightweight browser tool for cleaning up Gamma-exported PDFs without uploading files anywhere. It inspects page annotations, strips the matching watermark draw block, and downloads a cleaned PDF back to the user.
Why it exists
Gamma exports are useful, but the embedded badge can be distracting when you want a clean archive or a professional handoff. This tool keeps the workflow private and fast by doing the entire job client-side.
Highlights
- 100% local processing — no backend upload step
