Universal AI Image Cleaner — Full Pipeline Privacy Tool

One-click privacy pipeline for AI-generated images: C2PA strip + SynthID sanitize + dwtDCT remove + humanize. For personal privacy control over your images. Files never leave your device.

Applies maximum disruption. If you want to preserve a specific signal for verification, use the targeted tools instead (C2PA Stripper, SynthID Sanitizer, etc.).

Intended use

  • Intended for personal privacy protection: removing metadata and watermarks from files you own before sharing online. Not intended for: academic dishonesty, platform ToS circumvention, or misrepresenting content origin.
  • This tool applies maximum disruption. All AI-generation signals — C2PA, SynthID, dwtDct, and diffusion fingerprints — are removed or disrupted. Keep the original if you need to track provenance.
  • Watermark disruption is probabilistic. Vendors may update their methods at any time. This tool reduces detectability but does not guarantee elimination.

How to use

  1. Drop your image

    Drag any PNG or JPEG into the drop zone. The file is read in your browser and never leaves your device. The universal pipeline handles everything in one pass.

  2. Watch the stages

    The tool runs four stages in sequence: C2PA stripping, SynthID watermark disruption, dwtDct removal, and humanization. Each stage completes automatically — no input needed.

  3. Download the cleaned image

    The output is a PNG or JPEG with all AI-generation fingerprints removed or disrupted. Download the result with one click. The original file is never modified.

Frequently asked

What does this tool clean?

The universal cleaner runs four operations in one pass: (1) strips C2PA Content Credentials from the PNG iTXt chunk or JPEG APP11 marker, (2) disrupts SynthID invisible watermarks, (3) removes CompVis dwtDct invisible-watermark signatures used by Stable Diffusion, and (4) applies micro-blur, resampling, and film grain to humanize residual diffusion-model fingerprints. It targets every major vendor: OpenAI, Google, Adobe, Microsoft, Stability AI, and others.

How is this different from the individual tools?

Each targeted tool — C2PA Stripper, SynthID Sanitizer, DWT/DCT Watermark Remover, AI Image Humanizer — handles one specific signal. The universal cleaner chains them all together into a single click. If you need to preserve one signal for verification while removing others, use the individual tools instead.

Does this affect image quality?

C2PA, SynthID, and dwtDct operations operate on metadata and invisible watermarks — they do not touch visible pixels. The final humanization stage applies subtle micro-blur and film grain (strength 0.3) which may be perceptible side-by-side but is designed to be nearly invisible. For maximum fidelity, use the individual tools and skip humanization.

Are my images uploaded?

No. All processing runs in your browser. The pipeline uses canvas operations, ArrayBuffer manipulation, and Web Workers — no server is involved. The network counter in the header stays at zero.

Which vendors are covered?

C2PA: OpenAI (DALL·E / ChatGPT), Adobe (Firefly, Photoshop), Microsoft (Designer / Bing Image Creator), Google (SynthID), Stability AI (dwtDct watermark), and other C2PA-adopting platforms.

Limitations

  • Full pipeline onlyAll four stages run every time and cannot be selectively disabled. If you need to keep one signal intact while removing others, use the individual tools: C2PA Stripper, SynthID Sanitizer, DWT/DCT Watermark Remover, or AI Image Humanizer.
  • No detection capabilityThis is a removal tool, not a detection or verification tool. If you need to check whether an image is AI-generated, use the AI Image Inspector instead.
  • Humanization strength is fixedThe universal pipeline applies humanization at a fixed strength of 0.3. For adjustable strength or a visual preview, use the standalone AI Image Humanizer tool.

Platform notes

macOS
macOS Photos.app and Preview do not strip C2PA or SynthID metadata. This tool is the fastest way to clean AI-generated images before sharing on iMessage or social media.
Windows
Microsoft Photos and Paint do not strip AI metadata. This tool is the fastest way to clean images locally without installing any software.
Linux
CLI alternative: exiftool with -overwrite_original can strip specific metadata chunks. The universal pipeline is faster for batch processing multiple signals at once.
Web
Runs entirely client-side. The pipeline processes images in a Web Worker — the UI stays responsive during heavy operations.
