The watermark is applied at the picture's full size (up to 8000 px on the long side).

Are my pictures uploaded anywhere?

No. The watermark is drawn inside your browser, so the pictures stay on your device.

Can I watermark many photos at once?

Yes. Add up to 30 pictures, set the watermark once and download them all as a ZIP. The watermark is placed in the same relative position on every picture, even if their sizes differ.

Which position and style works best?

A small semi-transparent mark in a corner keeps the photo clean. To discourage copying, use "Repeat across the whole picture" with low opacity and a slight rotation.

Will the quality drop?

The watermark is applied at the original size. Choose PNG for no loss at all, or JPG / WebP with 90% quality for a much smaller file.
