About this tool

What add watermark to image does

The watermark tool draws text or a selected logo over the image locally. You can control size, opacity, rotation and placement before creating the output.

Privacy by design

Why local image processing matters

Routine image editing should not require unnecessary disclosure of personal files. When the browser can perform the task safely, Ryo Tools keeps the image on the current device instead of sending it to a remote image-processing API.

Common questions about privacy, browser support and results.

Is add watermark to image free?

Yes. This browser-based Image Toolkit operation is free to use and does not require an account.

Is my image uploaded?

The toolkit is designed to perform this operation locally in your browser. The selected image is not intentionally uploaded to Ryo Tools by this plugin.

What happens if my browser does not support the format?

The tool will show a visible error instead of silently failing. A current version of Chrome, Brave, Edge, Firefox or Safari is recommended. You can also try another supported format listed in the upload area.
