- Zero server contact: All processing happens locally in your browser using the Canvas API.
- Instant results: The algorithm runs in milliseconds.
- Lossless output: Exports as PNG with no recompression artifacts.
- No account needed: No sign-up, cookies, or tracking.
- Supports both watermark sizes: Automatically handles 48×48 and 96×96 watermarks.
- Browser extension available: For automatic removal on download from Gemini.
