description: Remove the visible Gemini AI watermark from images using reverse alpha blending. Use when asked to strip Gemini watermarks, batch-process Gemini images, or build/modify a CLI script that removes the bottom-right Gemini watermark without HTML or server-side components.

Gemini Watermark Remover

Dependencies

  • •Python 3.9+
  • •Pillow (install with pip install -r requirements.txt)

Quick start

  1. •Install dependencies in the scripts folder:
    • •cd skills/gemini-watermark-remover/scripts && pip install -r requirements.txt
  2. •Run the CLI:
    • •python remove_watermark.py <input-image> <output-image>

CLI usage

  • •Parameters:
    • •input-image: path to the Gemini watermarked image
    • •output-image: path for the cleaned image (format inferred from extension)

Example:

code
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

  1. •Use remove_watermark.py for one-off processing.
  2. •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.
