Is it private and secure?
Your privacy is built in. Add Watermark does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.
Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.
You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

Why Browser-Based Tools Are Safer for Your Files — Most online converters upload your files to a server. Client-side tools don't. Here's why that difference matters for privacy.
Frequently asked questions
Can I use my own logo as a watermark?
Yes. Switch to ‘Image / logo watermark’ and upload a PNG (transparency is preserved). Adjust its size, opacity, rotation and position.
How do I watermark many images at once?
Add all your images, configure the watermark once, and apply it to the whole batch. Download everything as a ZIP.
Can I tile the watermark across the image?
Yes. Enable ‘Tile across image’ to repeat the watermark on a rotated grid — useful for strong copyright protection on previews.
Are my images uploaded?
No. Watermarking is done locally on a canvas in your browser; nothing is sent to a server.
