You cannot fully stop AI, but you can make edits of your photos fail or look fake.
Why AI edits go wrong on protected photos
AI editors first "encode" a photo into a compact code, then edit that code. Photo Shield changes your pixels very slightly so that code points to the wrong picture. The editor then works from a blurry, washed-out version, and the result looks fake.
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.
