No image is 100% AI-proof, but you can make AI edits of your photo much less convincing.
What "AI-proof" really means
An AI-proof image is one where AI edits come out broken or obviously fake. Photo Shield adds an invisible layer (the PhotoGuard "encoder attack") so the copy a Stable-Diffusion-style editor works from comes out broken and distorted. The tool shows you exactly what the AI sees and gives a protection score out of 100 for your photo.
How to use it (3 steps)
- Open Photo Shield and choose a JPG, PNG or WEBP photo. It stays on your device.
- Leave the bars on full protection (the default) and press Protect my photo. It takes about 1-2 minutes on a recent laptop.
- Check the protection score, then download the protected PNG and post that version.
Honest limits
- It is aimed at AI photo editors built on Stable Diffusion. It does not reliably stop ChatGPT, Gemini or face-swap apps.
- Screenshots, heavy compression and resizing weaken it. Post the downloaded PNG where you can.
- No tool can make a photo impossible to edit. Combine it with private accounts and posting fewer close-up face photos.
