What it does
Provides a Python CLI tool that strips the bottom-right Gemini watermark without requiring HTML or server-side components
Uses pre-captured watermark alpha maps (48px and 96px variants) and reverse alpha blending to reconstruct the underlying image
Supports any image format that Pillow can read and write, with output format inferred from file extension
Includes detailed algorithm documentation covering d
Installation Guide
How to use gemini-watermark-remover on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your machine
- ›Node.js 16+ with npm — verify with
node --version - ›Active project directory where you want to add
gemini-watermark-remover
Run the install command
Execute the skills CLI command in your project's root directory to begin installation:
Fetches gemini-watermark-remover from rookie-ricardo/erduo-skills and configures it for Cursor.
Select Cursor when prompted
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate gemini-watermark-remover. Access via /gemini-watermark-remover in your agent's command palette.
Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Gemini Watermark Remover
Dependencies
- Python 3.9+
- Pillow (install with
pip install -r requirements.txt)
Quick start
- Install dependencies in the scripts folder:
cd skills/gemini-watermark-remover/scripts && pip install -r requirements.txt
- Run the CLI:
python remove_watermark.py <input-image> <output-image>
CLI usage
- Parameters:
input-image: path to the Gemini watermarked imageoutput-image: path for the cleaned image (format inferred from extension)
Example:
python remove_watermark.py ./in.png ./out.png
What this skill provides
scripts/remove_watermark.py: CLI entry point and core algorithm.assets/bg_48.png,assets/bg_96.png: Pre-captured watermark alpha maps.references/algorithm.md: Math, detection rules, and limits.
Workflow
- Use
remove_watermark.pyfor one-off processing. - If you need to adjust detection rules or alpha logic, read
references/algorithm.md.
Notes
- The script uses Pillow for image IO and per-pixel edits.
- Output format is inferred from the output file extension by Pillow.
