Want to add watermarks on Android? This app should do it:
@itsfoss That statement about protecting isn't actually truth. Even watermarking don't stop content thieves from removing watermarks pretty easily from any picture. There are plenty of apps for doing that together with the shitty ai powered ones as well.
If you really want to protect your images from any fraud, just don't publish them nowhere. There's unfortunately no other way to keep them safe today.
