💧 Add a watermark to your photos

FAQ
Are my images uploaded to a server?
No. Every operation runs entirely inside your browser using WebAssembly and on-device models. Your files never leave your device and are never sent anywhere. You can even disconnect from the internet after the page loads.
Can I watermark many photos at once?
Yes. Drop a batch, set the watermark once, and download every stamped image together in a single zip file.
