Your files are not stored on our servers

StampedFor never receives your image. Everything - opening the file, drawing the watermark, saving the result - happens inside your browser, on your own device.

What actually happens when you pick an image

Choosing or dropping a file hands it to the page, not to the network. The browser opens it locally, draws it onto a canvas together with your watermark text, and shows you the result. No copy is sent anywhere, and nothing is written to disk until you press Download.

What the server does

The server has one job: send you this page, its stylesheet and its script. It has no upload endpoint and no storage for images, so there is nothing for us to keep, read, log or lose. Once the page has loaded you could disconnect from the network entirely and the watermarking would still work.

What is remembered

Only your watermark settings - the text, colour, transparency, angle, margin and size - are saved, and only in your own browser's local storage so the tool looks the same next time. They never leave your device, and clearing your browser data removes them. Images are never stored, not even locally: close the tab and the image is gone from the page.

The downloaded file

Download renders the watermark at the image's original resolution and saves the JPG straight to your device through the browser's normal download mechanism. That file is yours alone - we never see it.
