About this tool
Stamp your name, handle or copyright across a picture with this in-browser watermark tool. Type your text, then set its position, size, colour and opacity until it sits exactly where you want β bold across the centre to deter theft, or a subtle corner credit. When you are happy, download the watermarked copy. The image is drawn on a canvas on your own device and is never uploaded to a server, so even unpublished work stays completely private while you mark it.
Frequently asked questions
Why is the watermarked file a new image?
The watermark is painted onto a copy of your picture on a canvas, then exported as a fresh image file, so your original stays untouched on your device. Because the text becomes part of the pixels, it cannot be peeled off in an editor the way a separate layer could β and that is exactly what makes it a watermark rather than an overlay someone could simply switch off or delete.
How visible should I make the watermark?
It is a trade-off. A faint, low-opacity mark keeps the picture looking clean but is easier to crop or clone out; a bold, larger one across the middle is far harder to remove but more distracting. For sharing proofs or protecting photos online, many people place a semi-transparent line of text over the main subject, so it cannot be cropped away without ruining the image itself.
Is my image uploaded to add the watermark?
No. Adding the text and exporting the result happen entirely in your browser on a canvas, so your image never leaves your device and is not sent to any server. That matters for watermarking, because the files you most want to protect β unreleased photos or client work β are exactly the ones you would least want to hand to a third-party website.
