Free Online AI Watermark Removal Tool
Prompts.Skin AI Watermark Remover detects and removes three layers of AI provenance: visible overlays (Gemini sparkle), invisible pixel watermarks (SynthID inferred from metadata), and file metadata (C2PA, EXIF, IPTC Made with AI). Upload PNG, JPG, or WebP up to 15 MB. Choose Quick Clean for visible + metadata removal, or All-in-one for invisible watermark disruption. All processing runs locally in your browser.

FAQ
- Quick Clean removes visible Gemini sparkles and strips C2PA, EXIF, IPTC, and PNG AI metadata. All-in-one also applies frequency perturbation to disrupt invisible SynthID-style pixel watermarks.
- Use Quick Clean when you only need visible logo removal and metadata clearing. Use All-in-one when the image was AI-generated and may carry invisible SynthID or similar pixel watermarks.
- SynthID requires GPU diffusion regeneration for reliable removal. Our All-in-one mode applies browser-based frequency perturbation as a best-effort disruption. For forensic-grade SynthID removal, use the remove-ai-watermarks Python library with a GPU.
