Prompts.SkinAI Image Prompts

Remove AI Watermarks

Upload PNG, JPG, or WebP. We detect every AI watermark and metadata signal, then remove them.

PNG, JPG, WebP — max 15 MB

Visible AI watermarks

Erase overlays like the Google Gemini sparkle using reverse-alpha blending.

Invisible watermark patterns

Disrupt hidden pixel-level markers like SynthID via controlled frequency perturbation.

AI metadata & provenance

Strip EXIF AI tags, PNG text chunks, and C2PA Content Credentials.

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.

Three ways we clean your images

Visible watermarks

NCC template matching finds the Gemini sparkle; reverse-alpha blending recovers original pixels.

Invisible patterns

Frequency perturbation disrupts SynthID and similar pixel-level watermarks (best-effort, browser-based).

AI metadata

Strip C2PA manifests, EXIF generator tags, PNG workflow chunks, and IPTC AI disclosure fields.

100% local

No upload, no account. Your images never leave your device.

FAQ

What does this tool actually remove?
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.
When should I use Quick Clean vs All-in-one?
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.
Can you fully remove SynthID?
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.
Which formats are supported?
PNG, JPEG, and WebP up to 15 MB.
Are my images uploaded?
No. All detection and removal runs locally in your browser.
Which AI models are supported?
Google Gemini/Nano Banana (visible sparkle + SynthID), ChatGPT/DALL-E (C2PA), Stable Diffusion (PNG params), Midjourney (EXIF), ByteDance Doubao/Jimeng (TC260), and more.
