Can I customize the watermark text?
Yes, you set the exact text used for the watermark.
Can I control how visible the watermark is?
Yes, opacity and font size are both adjustable, so the mark can be a subtle overlay or a bold, hard-to-remove stamp.
Is my image uploaded anywhere?
No, the watermark is drawn onto the image locally, in your browser.
