Add a Watermark to Your Image
Stamp your name or © line onto a photo before it travels — position, opacity and size under your control, at full resolution.
Private by design: this tool runs entirely in your browser. Your files are never uploaded to a server, and nothing is stored.

The watermark is stamped on your device — the photo is never uploaded
How to use it
Choose a photo. It loads onto a canvas at full resolution — a copy, so your original is untouched.
Style the mark. Type your text, pick a corner (or the centre for proofs), and tune opacity and size while the preview updates live.
Download the PNG. Stamped, full-size, ready to post — the photo never left your device.
Credit that travels with the picture
Photos get re-shared stripped of their captions within hours of posting; the name inside the pixels is the only credit that survives the journey. A watermark also does quiet legal work: it announces ownership to anyone who finds the image out of context, which deters casual reuse and strengthens your position if reuse turns commercial. Doing it in the browser matters more here than anywhere — the whole point is protecting a valuable original, and uploading that original to a stranger's server to protect it would defeat the purpose.
