SellstampWatermark image
Add a text or logo watermark to photos in your browser, in a corner, centred or repeated across, with the size and opacity you choose. Works on a batch.
The same watermark goes on every image. Done in this tab, never uploaded.
Your file stays on your device
Your browser opens and processes the file itself. It is never uploaded, to Sellstamp or anyone else, and nothing is kept after you close the page.

How to use it
- Choose or drop your images.
- Type the watermark text, or choose a logo.
- Pick the position, size and opacity.
- Add the watermark and download.
Your images are not uploaded
Your browser opens the image, does the work in this tab, and saves the result back to your device. Nothing is sent to Sellstamp or anyone else, so there is no upload to wait for and no copy on a server afterwards.
Visible, not unbreakable
A watermark tells people whose image it is and discourages casual copying. A small corner mark can be cropped off; a mark repeated across the image is much harder to remove. Neither stops a determined person, so keep originals private if that matters.
The text is drawn with a soft shadow so it stays readable on both light and dark parts of a photo.
Questions
How do I watermark many photos at once?
Add them all; the same watermark goes on each, and they download as a zip.
Which position is hardest to remove?
“Repeated across” covers the whole image, so it cannot simply be cropped off.
Can I use my logo?
Yes. A PNG or SVG with a transparent background works best.
Does it reduce quality?
PNG is unaffected. JPG is saved again at 92%, which is not visible.
