How to add a watermark to images

  1. Add your photos — up to 100 at a time.
  2. Type your watermark and choose position, size and opacity.
  3. Click Watermark and download the stamped photos.
Are my images safe?

Yes. Your images are only used to create your result — they’re never shared and never used to train AI.

Which position is hardest to remove?

Tiled (repeated) or diagonal watermarks cover the whole picture, so they can't simply be cropped off. A corner mark is subtler but easy to crop.

Can I use any language or symbols?

Yes — the text is drawn with your system's fonts, so accents, other scripts and symbols like © and ™ work.
