When this tool is useful
Preparing previews, portfolio images, proofs, and shareable drafts with a visible ownership or status mark.
How local processing works
The image is decoded to a canvas, text is drawn with opacity and rotation, and a new image is encoded in the source format.
How to use it
- Choose the source files.
- Review the available settings and page order.
- Process locally, inspect the result, and download it.
Important limitations
Output is re-encoded and metadata is not preserved. A visible watermark can be cropped or edited and is not cryptographic ownership proof.
Private by design
Your files stay in this browser. The tool does not upload the source or output to our servers.
