Who we are
The Watermark Generator is a free, no sign-up online tool for adding watermarks. Our goal is simple: make watermarking easy, fast and safe — just open the page and start, no software to install.
Whether you are a photographer protecting your work, a professional marking contract drafts, or a creator signing course materials against unauthorized reposts, this tool has you covered.

Privacy & data security
Your file contents never leave your device. We do not store, inspect or relay any uploaded file on a server — watermarking and exporting happen entirely locally.
Templates (including uploaded watermark images) are stored only in your browser's local storage; clearing browser data removes them completely.
To keep the service free, the page loads third-party advertising scripts, which may use cookies as is customary in the industry. Apart from that, we collect no personal information.
