Type your text (or upload a transparent PNG logo), pick a position on the 3×3 grid, set size and opacity, and the watermark is applied consistently to every photo in the batch — scaled proportionally so it looks right on portrait and landscape shots alike. A live preview shows the first photo exactly as it will be exported.

The tile mode repeats the watermark across the whole image in a staggered pattern, which makes it much harder to crop out — useful for proofs and previews you share before payment. Combine with resizing and compression in the same pass, then download everything as a ZIP. Your photos stay on your device throughout.

Frequently asked questions

Can I use my own logo as a watermark?
Yes — upload a PNG (transparency supported) and set its size as a percentage of the image width, so it scales naturally across different photos.
Will the watermark look the same on all my photos?
Yes. Size and margins are relative to each image's dimensions, so the watermark keeps the same visual proportion whether a photo is 800 px or 8000 px wide.
Can a watermark be removed by someone else?
A corner watermark can be cropped out; the tiled mosaic mode covers the whole image and is much more resistant. For valuable work, use tiling with moderate opacity.
