Picture Watermark - WaterStamp

This app lets you easily add text watermarks to images and videos. It’s completely free and doesn’t require registration or login.

Main features include single watermark, full-screen wallpaper watermark, and options to adjust text size, density, and opacity. You can also make text transparent to blend it with images.

With 500 new fonts available, you can create unique watermarks that stand out.
The app also includes special fonts to help resist AI watermark removal. Dot fonts and random rainbow colors make it harder for AI to recognize and remove the watermark. While it doesn’t guarantee complete removal, it has shown some effectiveness.
