Invisible AI tags, removed

Your images.
No invisible tags.

AI generators hide a SynthID watermark and a C2PA record inside your files — and platforms read them to label your work “Made with AI”. ClearMark scrubs both out, in your browser, so the file is fully yours again.

What gets removed

SynthID signal

The invisible watermark Google weaves into the pixels of Gemini, Veo and Nano Banana output. It survives crops and re-saves — so we disrupt it in the frequency domain, where it lives.

C2PA record

The signed “AI-made” provenance tag attached to the file. We strip it completely, along with EXIF and other metadata.

Generator metadata

Model names, prompts and tool fingerprints hiding in the file header. Gone — the output carries no record of where it came from.

How it works

  1. 1 · Drop your fileAn image from ChatGPT, Gemini, Nano Banana or any generator. It loads straight into your browser.
  2. 2 · We find the signalThe engine reads the image in the frequency domain and locates the watermark pattern across the pixels.
  3. 3 · We rewrite it outTargeted adjustments break the signal apart while the picture stays pixel-identical to your eyes.
  4. 4 · Download cleanA fresh file with no metadata, no C2PA tag, and a disrupted watermark — ready to post.

Honest note: no remover can promise 100%. SynthID is built to be stubborn, and detectors keep changing. ClearMark is best-effort by design — and we tell you how to verify it instead of asking you to trust us.

Quick answers

Is my file uploaded anywhere?

No. Everything runs in your browser. Your file never leaves your device, and we keep no copy.

Will the picture look different?

To your eyes, no. The changes are far below what humans can see — that is the whole idea.

Is removal guaranteed?

No — and any tool that promises that is overselling. SynthID is designed to survive edits. We disrupt the signal as far as current methods allow, and we point you to Google's free detector so you can check the result yourself.

Is this legal?

Use it on content you own or have the rights to. Removing a watermark to misrepresent where content came from can break platform rules — that responsibility stays with you.
