GPT Watermarker is a dedicated tool for stripping every watermark that Google’s Gemini models embed in generated images.
- Visible sparkle logo removal – done instantly in the browser using reverse alpha blending, reconstructing the original pixels without blur or quality loss.
- Hidden watermark removal – server‑side frequency‑domain processing that eliminates the invisible SynthID signal and the C2PA manifest together.
- Supports PNG, JPG, WebP uploads at any resolution, with drag‑and‑drop or clipboard paste.
- Free tier offers a daily allowance of visible logo removals; paid subscriptions unlock unlimited visible removals and provide credits for SynthID/C2PA cleaning.
- All processing respects user privacy – images are stored in account‑scoped storage and never used for model training.
Targeted at designers, developers, and professionals who need clean, presentation‑ready AI images or must ensure their content passes automated provenance checks on stock libraries, social platforms, or content audit systems.
