Frequently asked questions
- Can the watermark be removed by someone else?
- A visible watermark discourages casual reuse but can never be made impossible to edit out. Tiled placement across the image is the hardest to remove cleanly.
- Can I use an image or logo as the watermark?
- This tool stamps text only. For a logo, add it to a transparent PNG first, or use the Canvas tools in the TopScanner app.
