# Gamma Watermark Remover

Remove the "Made with Gamma" badge (image + gamma.app hyperlink) from Gamma.app exports. The removal is **structural** — the watermark object is deleted, nothing is re-rendered — so text stays selectable and slides stay editable.

## Steps

1. **Check the file**: only `.pdf` and `.pptx` are supported. Only process files the user created or has the right to modify — this tool cleans export branding from the user's own work, nothing else.

2. **Ensure the CLI is installed**:
   ```bash
   gamma-watermark-remover --version || pipx install gamma-watermark-remover || pip install gamma-watermark-remover
   ```

3. **Run the removal** (writes `<name>-no-watermark.<ext>` next to the input by default):
   ```bash
   gamma-watermark-remover deck.pdf
   gamma-watermark-remover deck.pptx -o clean.pptx   # custom output
   gamma-watermark-remover exports/*.pdf              # batch
   ```

4. **Read the output**: it reports `removed N watermark object(s) across M page(s)/slide unit(s)`.
   - `removed 0` → the export probably has no standard badge, or it was flattened.
   - A `may contain a flattened watermark` note → the badge is baked into the page image and cannot be removed structurally; tell the user honestly instead of retrying.

5. **Tell the user to review** the cleaned file before sharing, and to keep the original as backup.
